Hello,
I'm getting an error when trying to run a script. Part of the scripts is
Line 10 my $action = param('form_action');
.
Line 14 Search_DB() if($action eq 'search');
The error I get is:

Try setting a default value when 'form_action' isn't specified:
my $action = param('form_action') or '';
Or set it to 0, or 'do nothing' or undef, or whatever is appropriate.

Good catch. Yes, that's clearer than simple apostrophes.
However, you probably didn't really mean | | over ||, right ? :-)
I still think

Hello everyone,
Fairly new to the list here (and perl), so if this is an inappropriate
post, please forgive me. I've got the Learning Perl book plus a few
others...but I'm still scratching my head over this one.

Hello everyone,
Fairly new to the list here (and perl), so if this is an inappropriate
post, please forgive me. I've got the Learning Perl book plus a few
others...but I'm still scratching my head over this one

idea of which value is uninitialized.
