Now you see what I was trying to explain. :) So - go look at the rule on the button - I added one rule. It sets the query field in your data connection to the product type that you entered. Then, when the query runs, only the matches are returned. Now, you will need to handle for the case where no matches are returned. Want me to set up the rules for that for you? And you also should be doing this as part of your submit rules (because otherwise, if a few people have the form open at the same time, you could end up with multiple people with the same number) but this at least gets you headed in the right direction.
