Hello All,
One I am new to SF and Apex and their triggers, but I wrote this trigger and at one time it worked in Dev. Now it is not updating the list, with all my system.debug statements it gets all the way down to the update lstCase; statment but then errors out.
Can someone help me out on what might be happening now.
Thanks,
Keith.
