I want to develop a code to index a field in my table. For example, the Word Chrysler is the company name from the part order. Every time Chrysler is typed I want to start another field that indexes a letter and a number. Say Chrysler is in my form/table 10 times I want the corresponding field to auto generate A1,A2,A3,A4,A5,A6,A7,A8,A9,A10. Then once it hits 10 to go to B1, B2..... and so on. Is this possible??
