It would not David Burgun as provided the longer-winded explanation (and a great one at that - not meant as putting it down), but basically the "try" construct here lets me set the field to empty without running into a runtime error. Without the try the code would give me an error on the first line if pValue is empty, since it would try to execute if < 0 then Putting the code inside a try construct lets me ignore the error that results from trying to execute an illegal statement and move on to the next line of executable code after the end try. -- -Mark Wieder [EMAIL PROTECTED] _______________________________________________ use-revolution mailing list [email protected] Please visit this url to subscribe, unsubscribe and manage your subscription preferences: http://lists.runrev.com/mailman/listinfo/use-revolution
