How to Remove multiple items from sharepoint list based off items items in a collection

[Becca51178]

I can't figure this out. 

I have a collection with a list of items the user has selected. I know how to take that list and patch it to an existing sharepoint, but how do I take the same list and remove those items from a different sharepoint list. 

The formula below only lets me remove 1 item. 

Remove(UnregisterProjectSignUpList,

First(Filter(UnregisterProjectSignUpList,Title=Unregister_EventName_Txtbx.Text && Signee.DisplayName = Var_OfficeName)));

I know it's not going to work because it's referencing the first text box in the gallery. I can't figure out how to say ForALL or all selected items and make it work. 

The sharepoint list to remove the items is called UnregisterProjectSignUpList and the collection with all the items needing to be removed is called User_UnregisterProjects_Selections

Anyone know how to make this work?

You can use RemoveIf(). The syntax would look like this:

RemoveIf(UnregisterProjectSignUpList,Title=Unregister_EventName_Txtbx.Text, Signee.DisplayName = Var_OfficeName)

Does the User_UnregisterProjects_Selections collection have the ID number of the item you want to remove from UnregisterProjectSignUpList?

RemoveIf(UnregisterProjectSignUpList, ID in User_UnregisterProjects_Selections)

No and I don't understand why I can't get the ID to pull into the collection. Every time I try to put it in the collection it shows as blank

Can you show your code used to pull in the ID and also a screenshot of what the collection looks like in the viewer?  I would be curious to figure out why ID is not pulling in.

Ok give me 15 mins to get home

Feel free to jump in if you see the solution first or the reason why ID might not be pulling in.

I thinking I'll have to see the code here.  I have not encountered any issues with ID before.

[Becca51178]

Ok it was my mistake. I had the ID pulling in the first collection, but not in the collection where I added columns

The RemoveIf worked awesome. Thank you so much!
