Thanks, Uri. I didn't catch that.
I didn't write this script. I'm using it to learn from and cleaning it
up at the same time. I know that learning Perl from an older script probably
isn't the best way to do it, but since I have a vested interest in how this
script works, it's forcing me to learn it faster than I would otherwise.
However, if anyone knows of a shopping cart written in modern perl, I'd love to
have a look.

Actually, it's being used on an HTML template and just makes the HTML
code look cleaner.

I wasn't very clear in what I wanted. Sorry. I wanted to use the
value of $name in another loop but after testing, it looks like Shawn was
correct when he wrote:

I actually had to use another variable in the second loop to grab the
name.
Thanks to everyone who responded. I got it to work now.
