What are you doing with the 'untainted' data?

I found out where the problem is. I'm combining the symbol with a date generated. The file is supposed to be a stock symbol chart I have stored on my local drive. So I'm using the following code to see if it exists or not:

my $extx = ".jpg";
my $fx = "2006-01-05";
if( -f "D:/stock_charts/$symbol$fx$extx" ) {
    $filename = $fx;
    $com_hash{'num'} = "$filename";
    last;
              }
#so the filename should look like "AIDO.OB2006-01-05.jpg"

I think it has something to do with the proper tainting also. I'm going to try turning taint mode off to see if it stops it from timing out.

Thanks
