I have 2 unrelated tables "customers" and "categories"
customers has 2 fields custID and custName
categories has 2 fields catID and CatName

I have a 3rd table custcats that I want to insert Data into. I want to insert a unique ID into custcats that is custID combined with catID.

So if custID was 5050 and catID was 99 I would want the custcatID to be 505099. I want one row inserted for each combination of custID and CatID.

How would I go about achieving this?
