Power Platform Community Forum Thread Details

I have a form which is link to a sharepoint list in the backend. The sharepoint list has different column types such as Choice, Person. In the power apps, i have a form with combo boxes, dropdowns in the form. In the form i have done all the fields as required fields.For some boxes such as text input, the form displays automatic error messages on clicking on Submit button(Onselect= SubmitForm(form1). But on other fields such as Combo boxes(linked to a person type column in the sharepoint list) and other dropdowns , it does display any error messages. Please tell the correct way to display automatic error messages on clicking on submit button. I need the help urgently to update in my company project.

Hi @upadharp ,

Are you having problems updating the person column using combo box? It may be that you are missing some required values for the updater column during the update.

Could you show me the Items of your Combo box?

I'm assuming that your combo box's Items comes from the values in a person column, and you want to update the option to the person column of another table when you click the submit button. Then you can do this:

1)Create a collection to save values of person column:

ClearCollect(pp,ShowColumns(AddColumns(List1,"DisplayName",PersonColumn.DisplayName),"DisplayName","PersonColumn"))

2)Set the Items of Combo Box:

pp

3)Set the fields of Combo Box:

4)Set the Update of Card:

DataCardName.Selected.PersonColumn

Hope this helps you!
