nagios plugins return code issue

Ahh - I just realized something... I got the same response in Nagios when I uncommented "use strict;", but not at the command line. I get the following at the command line with it commented out:
If I run:
./checkciscotemp.pl -C '<community>' -H <ipaddress>
I get:
OK Inlet Temp: 18 Outlet Temp: 22
Then if I do a:
echo $?
I get:
0
But with "use strict;" uncommented at the command line I get a whole range of requirements that I need to define for global symbols such as:
Global symbol "$hostname" requires explicit package name at checkciscotemp.pl line 59.
I can try defining them and see where that gets me first. I did try looking a little for another script, but I guess I'll have to try harder as this seems to be most likely too outdated for the new version of nagios.

What is your command line? Are you calling the script directly or is it wrapped in a shell script? I took a quick look at the script, and it needs quite a bit of improvement. Not sure if it was a result of my copy and paste, but there is only so much I can blame on bad formatting. I would recommend looking for a different script that does the same thing.

Umm... Not sure. I just tried uncommenting and got the same results though.
I'm taking over managing the nagios server that we have from another collegue who left the company. I've actually migrated everything over to another server that is now running the latest nagios. The previous server was 3.0.6 I believe. I tried searching for an updated version of these plugins, but couldn't find any. I'm not that great with perl scripting either. :/

For starters, why is use strict commented out?

Hello all,
I've googled around everywhere trying to find an answer here and came up unsuccessful, so if anyone has had experience in this situation, I'd appreciate help!
Basically, the issue that I'm having is that I have a couple of temperature plugins that are reporting errors in Nagios and at the command line they're exiting in 0:
check7204temp.pl - Return code of 255 is out of bounds and checkciscotemp.pl - Return code of 9 is out of bounds
If I run a "echo $?" at the command line after running the command successfully, I get 0.
Thanks for any help anyone can provide!! My perms are 755 and nagios user owns the plugins and I've run successfully with nagios user and got 0 output. I'm really stumped!!
Here's the code for the plugins:
