Undefined subroutine

[Barry Veinotte]

Hi folks,

I am trying to get a program to run under mod_perl using Apache::Registry
and am getting the following error:

Undefined subroutine &Apache::ROOT::cgi_2dbin::ads1::ads_2epl::handler
called at /usr/lib/perl5/site_perl/5.005/i386-linux/Apache/Registry.pm line 135.

I am working with Red Hat Linux  6.2

I am totally new to this, and have no idea what this error is telling me.
If someone could point me in the right direction I would greatly appreciate it.

Thanks,
Barry
