[Koha] inventory.pl not working for me

[Matthew Metzger]

Hello,

sorry to deluge the list with so many posts. This is my time to work on 
our library system and I have to address a few different things all at 
the same time.

When I go to Accounts and Reports > Inventory/Stocktaking > 
inventory.pl, enter in some values, and then press the "Generate Report" 
button, I get nothing. My template of choice is NPL, but I also tried it 
in the default template and it doesn't work there either.

Here's my system stats:

Koha version:  	2.2.9
OS version (from 'uname -a'): 	Linux ubuntu-server1 2.6.15-28-powerpc #1 
Thu May 10 09:50:21 UTC 2007 ppc GNU/Linux
Perl version: 	5.008007
MySQL version: 	mysql Ver 14.12 Distrib 5.0.22, for unknown-linux-gnu 
(powerpc) using readline 5.1

thanks for your time and any help you can give me.
