Yea what I was thinking is from webmin 

error(message) This function is typically used by CGI programs that process 
the input from a form, to inform the user of invalid input or some processing 
error. It assumes that a global variable called $whatfailed contains the 
first part of the error message, with the parameter being the rest. For 
example :

$whatfailed = "Failed to save user";
if (!$in{'name'}) { &error("Missing username"); }
if ($in{'name'} =~ /a/) { &error("'$in{'name'}' is not a valid username"); }

dunno if any of this would be more useful or not... I might have more 
comments after doing more merging of the code today....
