Hi there,
It looks like I'm running into some weird issue that is causing me some problems. I have written a report script that uses DB connection to retreive data based on which it creates the report. I had run it on my computer and works fine, however when I put it up on a server, it does not fully work. Both use perl 5.8.1. Now I did run a debug (use diagnostics;) that returns me the following:

Use of uninitialized value in concatenation (.) or string at
        ./class_report_final.pl line 92

[download]
The line looks like this: 
push(@MASTER, row[0].":".$row[1].":$matrix[$ab][3]:".$total_packages."
+:AI"); last SWITCH; }

[download]

I can't figure it out what is wrong. Can you help.
Thanks
