invalid array length error

I moved over an event sheet that generates terrain to a new project. For some reason every time I run it inside the new project I get an "invalid array length" error dialog.

I've tried everything, but no matter what it still errors. The only time it doesn't is when I disable the event that sets the size of one of my arrays. I know the problem is there, but no matter what size I set it to it says the same error.

Sorry for the lack of .capx, but it is part of a massive project.

Has anyone seen this javascript error before?

Are you sure the array is set to global, and are you also sure that the array is part of a layout that has already been executed before you try to execute your events ?

The arrays are global. What do you mean by making sure the array is part of a layout?

I switched them to local arrays and the error went away. Thank you for leading me down that path!
