Increment serial number separately for each model?

Post

     Hi, I'm brand new to FileMaker and trying to figure out how to automate a customer's existing serial numbering scheme.

     They sell several different models of knife, each model having a different alpha-numeric code, such as A1, A2, B5, B12, etc.  Each individual knife should be assigned a serial number that increments based on the model.  So the A1 knives are numbered A1-1, A1-2, A1-3, etc, and the B5 knives are numbered B5-1, B5-2, B5-3, etc.  Each time a new knife is entered into inventory, the user should be able to enter which model type it is, and the system should generate a serial number that increments from the highest serial number used so far for that knife model.

     What is the best way to set up such an autonumbering scheme?  Note that I am NOT trying to make this serial number my primary key for anything...I know what a bad idea that would be.

     I apologize if this question has been answered already, and I'd appreciate a link to such a post if that's the case. I did several searches and didn't find anything matching my problem.
