Validation of postcodes
Is there an easy way for FileMaker 10 to deal with the validation of postcodes or ZIP codes if in the US?
I want to be able to validate the following types of postcodes. Here are three examples.
- HT14 6GH - This one is acceptable
- 3RT B14 - This one is unacceptable because the first part starts with the number 3 and the second part starts with the letter B.
- S2 4PQ - This one is acceptable.
Not sure how to tackle this one in FileMaker. I believe in Access you would use input masks.
Any help appreciated
