Hi PowerApps Community,

I have a canvas app with Edit Form which is connected to a SharePoint list. There is a choice field on the from whose default value needs to be set to one of the choice options if its blank.

It works, when the 'Default" property of the datacard is set to the following expression.

LookUp(Choices('LisName'.'ChoiceFieldName'),Value="DefaultChoiceOption")

The requirement is to set default value only when the field is blank.

Using if condition to check if the datacardvalue is blank/empty results in "this rule creates a circular reference" error.

Looking for help to get the above accomplished.

Thanks,

Try this code instead:

If(ThisItem.ChoiceFieldName.Value=Blank(), {Value: "Default Text"}, ThisItem.ChoiceFieldName)

@mdevaney, Thanks for the response. I see error "Invalid argument type" in the expression for '=' operator.

I have edited my code above to include .Value. Please try it instead.
