Greetings all, I've been banging my head against this one for a couple hours now, but a lot of reading and experimenting with formula tricks hasn't gotten me anywhere.
Short version: How do I make a field on a panel refresh itself with a value from another related panel whenever the selected value in the data-linked field changes? This field should NOT be part of the data link key, i.e. I should be able to change it afterwards without breaking the link. Longer version: I'm making a small sales database for selling some stuff at a flea market later this summer. The issue here involves three panels: items, invoices, and invoice lines. The items panel has a price field, where I store the sticker price of the item. The invoices panel has a panel link to the invoice lines panel. The invoice lines panel has an item field, which has a data link back to the items panel, allowing for selecting an item. The invoice lines panel also has its own price field, because I may sell an item for a price other than what I had marked it (it's a flea market, after all). What I'd like to have happen is when I press F5 on the invoice panel link to create an invoice line item, the invoice line's price field gets automatically filled when I select a record in the item field using the up arrow. But I need the price on the invoice line to be updatable, and I don't want the change to cascade back to the items panel or sever the link. I tried adding a second field (which would eventually be hidden) to the invoice lines called "Selected Price", set to calculate as the sticker price of the selected item at any change. Then I had the main invoice line price field calculate something like this: IF [Selected Price] <> [Price Field In Items Panel] THEN [Price Field In Items Panel] ELSE [Price] ENDIF That didn't seem to get my anywhere, as I haven't found a way to convince DP to compute that field BEFORE computing the value for the "Selected Price" field. Any ideas? Thanks. -Dave Britten _______________________________________________ Dataperf mailing list [email protected] http://lists.dataperfect.nl/cgi-bin/mailman/listinfo/dataperf
