How can I allow a deployed script access a custom function

I'm fairly new at this, so this may be an obvious question. I have a script that I need to run in the background everyday via windows task manager using MCR. This script accesses custom functions. When I run the uncompiled version in matlab, it works fine. I cannot get the compiled version to run. My guess is that the custom functions are not on the path. I tried using addpath in my script and also tried packaging the functions with the script. I think I must be missing something pretty obvious. Thanks, Alex

Have you tried adding in a try/catch in order to print out what MATLAB thinks the problem is?
