Can someone tell me what this code is doing? I am new at Perl and am totally lost! I need this to use the customerNumber from the form and read a database to get information and display it until there is no more information for that number. In the database, there are mulitple rows of information for one customer. When I run this I get nothing. Why?.... 
while ($CustomerNumber = $Data{"CustomerNumber"}) {
         $db->Sql("SELECT * FROM Cust_act_da WHERE CustomerNumber = $C
+ustomerNumber AND #TransType = P");
         $db->FetchRow();
         ($TransDate, $TransPmtAmt) = $db->Data("TransDate", "TransPmt
+Amt");
         
         $FormatTransDate = substr($TransDate, 0, 10);
         $FormatTransPmtAmt = sprintf("\$%.2f", $TransPmtAmt);
    
         print $FormatTransDate;
         print "    ";
         print $FormatTransPmtAmt;
        }
