Remove the double quotes around [Inv.value]
You are trying to update the value in the existing field Stat.value, which is a data type Double
Is field Inv.value also a Double?

Hi @BillyL14 ,
Change the formula to
if [Stat.value] = 0 THEN [Inv.value] ELSE [Stat.value] ENDIF
It will work. Its a datatype issue
If this solves your task please mark the post as solution.
