The value of $app{"first_name"} is not changed to undef in &print_application but @errors is. print statements confirm both are changed inside of the "if (request_method() eq "POST")" block. Your statement implies that there is an issue with changing values in the %app hash within the print_application() function. Since you didn't show us the print_application() function nor did you show us the beginning of your script where you (correctly) have 'use strict;', I gave you the most common error which is a mispelling of %app. Some other possibilities include: Mispelling 'first_name'. Hash keys are case-sensitive. Declaring %app within print_application(). Using this script under mod_perl (or some other persistent environment like FastCGI). (You'd be getting a "%app will not stay shared" error, but you might not be looking at the error log.) Given the dearth of information, this is the best I can do. Good luck! Being right, does not endow the right to be rude; politeness costs nothing. Being unknowing, is not the same as being stupid. Expressing a contrary opinion, whether to the individual or the group, is more often a sign of deeper thought than of cantankerous belligerence. Do not mistake your goals as the only goals; your opinion as the only opinion; your confidence as correctness. Saying you know better is not the same as explaining you know better.	[reply]
