Thanks!

Use strict; unveiled a syntax error!

Check the following:

-The script is executable (chmod +x /var/lib/asterisk/agi-bin/script.pl)
-The script has the right interpreter in the head. (#!/bin/perl or
whatever `which perl` gives you - put this on the first line of
script.pl)

-If that doesnt work, run 'perl script.pl' from a shell on your asterisk
box and check for syntax errors. (Make sure to have 'use strict;' in
script.pl).
-If no syntax errors, try stepping through it by issuing AGI result
codes to the script if that what your script is expecting (e.g. "200
result=0" or whatever the rest of the codes are) and check for undefined
subs or something. 

It helps to 'use strict;' in your AGI scripts so that the interpreter
does variable name checking for you and it shows up when you run your
script from the command line.
