I am brand new to PowerApps and I am having a bit of trouble with updating a TextInput field B based on changes to TextInput field A only if field B is blank.I have had success with setting the default property of field B with
Default = DataCardValue25.Textbut if field A gets updated after field B is filled in it will change the value of field B again
Default = If(IsBlank(DataCardValue31), DataCardValue25.Text, "")
but I am getting a "This rule created a circular reference between properties, which is not allowed" error
I've also tried setting DataCardValue31.Text in the OnChange property of DataCardValue25 (field a) but I am not seeing success with this method either.
I must be missing something simple.
