Scrolling Game Development Kit Forum

Any idea what this error means?  The game will start up and run, but when I press control to try and swing a sword, the game crashes and that error comes up ("Error playing map: Subscript out of range").  I'll post the code if you need to see it to help... I'm sure the code is broken; I've made some massive changes over the original code, and deleted a lot of stuff that I thought wouldn't be needed in my script (or commented out stuff that I haven't implemented yet).
