Hi,
this post belongs in the Mach4 General Discussion board.

The script, ScreenScript.lua, is a file that gets composed of all the Lua fragments, they all get rolled into one file and compiled.

The fault occurs at line 1614 in that file.

My guess is that you have a poorly or incorrectly defined parameter and when Mach goes to compile the code it fails. That's what the
stack traceback is all about, and in particular the line number.

Note that even once you find the offending line you cannot edit ScreenScript.lua directly, you have to edit the source Lua fragment
which is incorporated into ScreenScript.lua.
