The best way to do a search

[MikeK]

I have a file called 'client.fp5' that opens up in browse mode showing an individual record for a client (name, address, phone, related invoices, etc.)

Here's the scenario....a customer calls and wants to place a service call, on this screen I just mentioned, I would like to be able to type in their last name, do a search, if it is found, then I could go to their record and create a new invoice, if no matching record was found, then I would have a choice of creating a new record for this client, after which point I could then create a new invoice.

What is the best way to do this?
