Hello,
I've got a table which I'm hoping to populate a hidden field (to be used in a look up for some eventualities) depending on the answer in a drop down earlier in the row. The drop down is a Yes/No and the idea is to fill the hidden field with the work Critical or Non-Critical. As it stands I've got the following in the calculation section of the hidden field:
=IF(INDEX(Engineering_Drawing.Critical,ROW()) = "Yes", INDEX(Engineering_Drawing.Drawing_Style,ROW()) = "Critical", INDEX(Engineering_Drawing.Drawing_Style,ROW()) = "Non-Critical")
However it's stating that this contains circular logic, as far as I can tell it's sound in that if the row reads yes, it should fill the second row with Critical, and if not with Non-Critical. Anyone know where it's falling over? Maybe I can't use direct comparison in the if statement?
