AE script error messages

[teedoubleyou]

Hey,

I'm having a bad time with one of my scripts, and I was wondering if anyone could clarify this message for me:

After Effects error: attempt to remove an item from a position outside of list length.

Any help would be greatly appreciated.

Thanks very much.

I managed to discover the origin of this message.

I was using an undo group, and well.. it wasn't working. So removed the undo group as it wasn't required anyway.

Sorry everyone.
