Hi,

So, what I have is the edit form page (where each variable has a default value to display) contains a select-one field with a static list.

What I want is to display the value of my variable that i get from the SDP.

what happens now, the field always displays the first item of the static list.

what i tried, i created an item text-binding with my variable and make it my first item also i disabled it (to not display the same value two time) but it display the variable expression
