Fetch Data

Fetch Data

Absolute beginner but I've spent hours trying to get Fetch Records when selecting a field in Form B.  I simply want other fields in Form B to be populated based on selection of data in Form A.

The example in the Zoho help is clear but doesn't seem to work when I transpose the fields to mine.

Form A so far is a basic Product List (Manufacturer, Model Number, Warranty).

Form B are Devices we actually have installed (so potentialy multiple Products of the same type), so want the Form B to reduce double entry by looking up the Product List from Form A .
