Okay >Let's walkthrough a sample :)

Check >-Create a new form, set Datasession to Private and add orditems, products to DE (delete relation - don't need it)
Check >-Create grid for orditems, selecting all fields in DE and drag&drop on form
Check >-Now we have a plain grid browsing orditems
Check >-Create a combo control on form (this is temporary but easier to play when not in grid)
Check >-Using builder set this combo's fields to products.Prod_Name, product_id, Style dropdown list, controlsource = orditems.product_id, boundcolumn=2
Check >-Select combo and Copy (or Cut)
Check >-Edit grid and select product_id column and paste

>-Change Product_ID columns controlsource to (as written in PEM sheet):
>

>(iif(seek(orditems.product_id,'products','product_id'),products.prod_name,''))

wait wait I have to use views, the whole thing hinges on it and okay, i'll to a index tag for trial purpose.
Check

Check >-AFTER this set bound = .f.
Check (Hadn't changed at design time yet) >-Go and change combo's controlsource back to orditems.product_id (should have changed to other iif(...
Check >-Set current control to combo
Check >-Increase rowheight slightly
Check >-Run

Index was not allowed on this view. Sorry to frustrate you :(. The grid went blank, guess we'll have to start with a clean slate <g>.
