Hi!

 

From the looks of things, it's just a small syntax error.

Just to make sure we're on the same page, in the section of code with the errors, if the lookup to LikeResponses is blank, you want to patch to LikeResponses and then patch to LikeCount? 

 

Going over the code, it looks like you're trying to surround these two patch functions in brackets to have them be performed together?

The syntax for this is slightly different. Assuming you're using an If function here, anything you want to be grouped together as one argument to the if statement should be separated with semicolons ";", and anytime you want to separate arguments, use commas.

 

Hopefully you're able to get it from this, otherwise could you send the full code here? Your earlier screenshot seems to be a little cutoff, so I've had to make some assumptions.

 

Let me know 🙂

I see he problem here - you need to remove the brackets around the multiple patch functions. However, it looks like potentially your order of operations in your if function was slightly off? There were two identical blocks of code(2 patch functions each) separated by a comma in the middle - since these won't work with the if function I removed the latter. Try this code and let me know if it works as desired. I haven't tested it but I did remove the extra brackets which could have been to blame.

 

If(
  SharePointIntegration.Selected.'Created By'.Email = User().Email,
  Notify("You can't like your own post!", NotificationType.Error),
  IsBlank(
    LookUp(
      LikeResponses, 
      UserID = User().Email && Title = Text(SharePointIntegration.Selected.ID)
    )
  ),
  Patch(
    LikeResponses, 
    Defaults(LikeResponses), 
    {
      UserID: User().Email, 
      Title: Text(SharePointIntegration.Selected.ID), 
      LikeStatus: 1
    }
  );
  Patch(
    LikesCount, 
    LookUp(LikesCount, Title = Text(SharePointIntegration.Selected.ID)), 
    {
      TotalLikes: Value(LookUp(LikesCount, Title = Text(SharePointIntegration.Selected.ID)).TotalLikes) + 1
    }
  ),
  LookUp(
    LikeResponses, 
    UserID = User().Email && Title = Text(SharePointIntegration.Selected.ID)
  ).LikeStatus = 1,
  Patch(
    LikeResponses, 
    LookUp(
      LikeResponses, 
      UserID = User().Email && Title = Text(SharePointIntegration.Selected.ID)
    ), 
    {
      LikeStatus: 0
    }
  );
  Patch(
    LikesCount, 
    LookUp(LikesCount, Title = Text(SharePointIntegration.Selected.ID)), 
    {
      TotalLikes: Value(LookUp(LikesCount, Title = Text(SharePointIntegration.Selected.ID)).TotalLikes) - 1
    }
  ),
  LookUp(
    LikeResponses, 
    UserID = User().Email && Title = Text(SharePointIntegration.Selected.ID)
  ).LikeStatus = 0,
  Patch(
    LikeResponses, 
    LookUp(
      LikeResponses, 
      UserID = User().Email && Title = Text(SharePointIntegration.Selected.ID)
    ), 
    {
      LikeStatus: 1
    }
  );
  Patch(
    LikesCount, 
    LookUp(LikesCount, Title = Text(SharePointIntegration.Selected.ID)), 
    {
      TotalLikes: Value(LookUp(LikesCount, Title = Text(SharePointIntegration.Selected.ID)).TotalLikes) + 1

@madlad yes you got it right on. LikeResponses and LikesCount are two seperate lists as well.

 

I tried to play with the comma and Semi colon but cant make it.

her is the code if you can see where i am missing:

 

If(

SharePointIntegration.Selected.'Created By'.Email = User().Email,

Notify("You can't like your own post!", NotificationType.Error),

 

IsBlank(LookUp(LikeResponses, UserID = User().Email && Title = Text(SharePointIntegration.Selected.ID))),

(

Patch(LikeResponses, Defaults(LikeResponses), {UserID: User().Email, Title: Text(SharePointIntegration.Selected.ID), LikeStatus: 1});

Patch(LikesCount, LookUp(LikesCount, Title = Text(SharePointIntegration.Selected.ID)), {TotalLikes: Value(LookUp(LikesCount, Title = Text(SharePointIntegration.Selected.ID)).TotalLikes) + 1})

), (

Patch(LikeResponses, Defaults(LikeResponses), {UserID: User().Email, Title: Text(SharePointIntegration.Selected.ID), LikeStatus: 1});

Patch(LikesCount, LookUp(LikesCount, Title = Text(SharePointIntegration.Selected.ID)), {TotalLikes: Value(LookUp(LikesCount, Title = Text(SharePointIntegration.Selected.ID)).TotalLikes) + 1})

),

LookUp(LikeResponses, UserID = User().Email && Title = Text(SharePointIntegration.Selected.ID)).LikeStatus = 1,

(

Patch(LikeResponses, LookUp(LikeResponses, UserID = User().Email && Title = Text(SharePointIntegration.Selected.ID)), {LikeStatus: 0});

Patch(LikesCount, LookUp(LikesCount, Title = Text(SharePointIntegration.Selected.ID)), {TotalLikes: Value(LookUp(LikesCount, Title = Text(SharePointIntegration.Selected.ID)).TotalLikes) - 1})

),

LookUp(LikeResponses, UserID = User().Email && Title = Text(SharePointIntegration.Selected.ID)).LikeStatus = 0,

(

Patch(LikeResponses, LookUp(LikeResponses, UserID = User().Email && Title = Text(SharePointIntegration.Selected.ID)), {LikeStatus: 1});

Patch(LikesCount, LookUp(LikesCount, Title = Text(SharePointIntegration.Selected.ID)), {TotalLikes: Value(LookUp(LikesCount, Title = Text(SharePointIntegration.Selected.ID)).TotalLikes) + 1})

)

)

@madlad Thanks alot. the error is gone and first part of code which involves LikeResponses and toggling feature for same user is working now. But unfortunately, LikesCount is not updating or getting any entries. But I think I can take from here 🙂

Sounds good, glad you've got the errors sorted! 🙂

I've accepted the solution to this one so others will be able to find it in the future easier.
