Things to check:
1) The file is found by FPSC and loaded properly. If the file was not found, this can cause a few different problems.
2) The name given to the hud is not used by another hud (esp. a hud that uses a differentimage file)
3) The proper script has been attached to your entity.
To check #1, place the item into a level by itself, with no other entities at all. This will prevent other scripts from interfering with your entity's script.
To check #2, Ensure #3 checks out for ALL other scripts in your level.
I suggest placing your entities one by one into a small, empty level, checking each one as you go, and checking every entity, every time, to make sure they all work well with each other.
