I have an question about my database. I have two fill in forms each having their own database. I want some of the fields that people have filled in to match with each other. For example, in form 1 a women filles in she has postal code 1234, and then I need to match this with someone who also has filled in she is in the same postal code, or a near by postal code. Then, the other fields she has filled in also need to be matched. Like grades.

It is not a dating site, but I think it requires a similar system.

I hope you can help me with my problem,
