global variables in subroutines..?

[Stephanie Stiavetti]

I'm writing a script to check for validity of form elements.  here's what I
have so far:

my ($job) = $cgi->param("job");

bla bla bla more script bla bla bla


sub fixFailed
{       my (@failedFields);
        my ($validForm)="1";
        
        #validate job selection
        if (!$job) {
                $job="job ";
                push (@failedFields, $job);
                
                }



my question is, I remember someone a while back mentioning that you should
NOT redefine global variables in your subroutines... what can I do as an
alternative?  what do I risk by doing it anyways?

And then the day came when the risk to 
stay tight in a bud became more painful 
than the risk it took to blossom.
