The problem is that I don't know how to do that given the database interface you're using. This is par t of the context problem I mentioned in my first post to your original question. It sounds like you're now saying $Data{CustomerNumber} IS somehow updated, say, by the $db->FetchRow call. But that's not something I, or anybody else unfamiliar with the database interface you're using, can tell just from looking at the code you've posted. So the best I can do is say, in the abstract, the steps you need to take. In pseudo-pseudocode, what you want is: 

1. prepare SQL statment to fetch all rows that 
 A) match the customer number the user has entered 
    and 
 B)have transtype 'P'.
2. execute SQL statement
3. while (there's another row in the set) {
  print out the data
}

It sounds like your database interface fetches the data "behind the scenes" and stores it in the %Data hash, which makes it extremely difficult to debug this kind of problem from over here.
