>I need to display on the grid in the form the following: invt.styleno, styles.desc, invt.size, invt.color, invoitem.price, invoitem.qty fields. The problem is, how should I setup the grid to display this in the easiest way? I've tried using param. view in a optimistic buffer mode but when I add new items, the lookup fields (fields based on INVT and STYLES table) aren't displayed, only fields based on INVOITEM.

Did you do an APPEND BLANK in all 3 tables?

>When I try to refresh the grid, I get an error that I need to update the view but I want the option to TABLEREVERT later so I don't want to update the view until the whole invoice is ready to be updated. Any suggestions on how I should set this grid up?

Personnaly, I don't do updates directly in the grid. I put command buttons ("New", "Modify", "Delete") and present a form for data entry.
