Why not have the link always lookup based on ID? If you've got the cartridge in hand, presumably the ID is readily available from the sticker, making the ID the common denominator of what's always available when posting the invoice entries.

I've got a database I use for selling old video games at garage sales and flea markets. It's only got 7 panels, and just three of those are relevant for this question. There's a panel for the actual games, with fields such as title (not necessarily unique - I may have multiple copies) and ID (a short 2-6 character sticker code that is unique per cartridge). There's an invoice panel that acts as the invoice header: invoice no., total price, etc. Then there's an invoice lines panel. This has an invoice no. field that links the lines to an invoice, and also title and ID fields that correspond to the Games panel via a multi-field data link. Right now the invoice lines panel is set up to link on title then ID, meaning if I create a new line item and press up to choose a game, I have to use the lookup that's defined based on title. But sometimes I (or my wife) might just scribble the sticker code on the receipt if pressed for time. I'd like to be able to select either field in the data link and do a lookup based on the chosen field, so I don't have to first manually go back and find the title based on ID via other means. I also have some keep-a-total fields in play to automatically set a "sold" field on the Games panel record when a game is linked to an invoice line, and also update the total for the invoice header. Is there a simple way to have a choice of lookups like that? I recall experimenting with this in the past and not having much success. (That may have been with more complex many-to-many scenarios, though. Invoice-line-to-game is zero-or-one-to-one.) -Dave Britten ________________________________ Dataperf mailing list [email protected] http://lists.dataperfect.nl/cgi-bin/mailman/listinfo/dataperf
