Initial Value on Enum

[Mark_11]

Hi,

i’ve tried many times and also read various threads, but still do not able to make it works.

I’ve a very simple Enum with 2 text options button, no Appformula, no Valid IF; it’s just everything blank.
i’d like to set “NO” as initial value because i guess it will be mostly right. I’ve tried with “NO”,NO,=“NO”; nothing happen.

thanks
