Hello Monks,

I am stumped yet again and need to call upon your infinite knowledge. I have the below sub routine but some of the databases it pulls are not valid so when the main body executes it stops/exits.

What I would like to do is keep the script going even if the connection fails - IE have it move onto the next element in the arary (database).

Right now (as you can see) I tried to put the connect into an if statement in the sub_rortine but it dosen't seem to work. This is new to me so not sure if I should just have something in the body or in the subroutine (like i have below)

#!/usr/bin/perl

use strict;
use warnings;
use DBD::mysql;
