Fellow monks, I've got a skull-scratcher that is beyond me. Any assistance would be greatly appreciated.

I have an Apache::ASP page that takes user input and posts it back to itself. My problem is that about every 3-5 times that I submit the form, the SENTDATA var isnt accessable from check_login_output.

Note: it works most of the time and I'm confused because this behavior is intermittent.

Here's the code

<%
use CGI ':cgi-lib';
my %SENTDATA = Vars;

print join('|', "1",$SENTDATA{UID},\%SENTDATA,"<br>");

if (! $SENTDATA{UID}) { 
  # no passed userid, show the input screen
  print join('|', "2a",$SENTDATA{UID},\%SENTDATA,"<br>");
  &amp;amp;amp;amp;amp;amp;amp;show_login_input();
} else {
  print join('|', "2b",$SENTDATA{UID},\%SENTDATA,"<br>");
  &amp;amp;amp;amp;amp;amp;amp;check_login_input();
}
$Response->End();
  
sub check_login_input {
  print join('|', "3",$SENTDATA{UID},\%SENTDATA,"<br>");
}

sub show_login_input {
  # html input <SENTDATA method='POST'>
%>

Here's the output from when it works:

1|506651|HASH(0x20656624)|
2b|506651|HASH(0x20656624)|
3|506651|HASH(0x20656624)|

Here's the output from when it doesn't work:

1|506651|HASH(0x20672eb0)|
2b|506651|HASH(0x20672eb0)|
3||HASH(0x202e110c)|

Now for the Question(s):

• 1. Why is SENTDATA only avaialable to check_login_input() intermittently?
• 2. When it does fail, why am I not getting an error in check_login_input() for the use of an undeclared var?

CGI.pm is the one that shipped with 5.6.1, I think it's 2.752
