Re: Project Lunch Management

I suspect the issue here should be caused by the source.

What is the Tableau1_2 contains?

This table in lookup function should be the LunchType table, which is the second data source added into PowerApp.

Re: Project Lunch Management

Hi Vkevin,

 

The following si the lookup function reference:

Filter, Search, and LookUp functions in PowerApps

 

I just added the TextBox under the Lunch form, then change the Text formula with the lookup function, this works from my side.

The first parameter of lookup used here is the lunchtype table, second part is lunchtype column name in lunchtype table equal to the selected value of lunchname dropdown, thrid parameter is another column newly added into lunchtype table, as the output value of lookup function.

 

You may take a try to manually input the parameters, check to see if this would make it work.

Re: Project Lunch Management

Hi,

 

I recreate completely the app since beginning and now, i got a different error message :

I translate the error message for you : "This rule creates a circular reference between the properties, which is not allowed. A property can not refer itself or reference other properties affected by its value"

 

Thanks for helping,

best regards.

Re: Project Lunch Management

OK.

 

Few things that you could take a try.

Option 1

First, Leave the original TextInput Box, Add the Dropdown box and change the Update and Y properties of the Lunch Card as before,

Then Modify the Textinput box Default formula with the lookup formula:

LookUp(Table1_1,LunchType=LunchName.Selected.Value,ingredients)

Option 2

Check your PowerApp Studio version, make sure the version is 2.0.542. If not, update your PowerApp Studio.

If issue still insists, duplicate your Lunchtype Excel in OneDrive for business, rename the lunchtype column to Lunchtype1, add this Excel as another data source, then modify the lookup formula to the one below:

LookUp(Table1_2,LunchType1=LunchName.Selected.Value,ingredients)

 

If still not working, please share the detailed steps that you have tried to create your app.

Thanks

Regards
