Intersperse print statements throughout your script (or writes to a log file, whatever's easier for you) so you can pinpoint the line within your code that's leading to the error within the window API - as Yami notes, it'll be one of the ones where you call a term function. Once you've figured out the culprit, have the script print out the values you're passing to the problematic term function before it goes ahead and does so. You'll then know which variable has the incorrect value, and can start work of figuring out how it got that way.
I actually made that on the original code. Ended up figuring out what the problem was. Apparently, the sColor variable should be declared either as a pointer (I believe this is the term for 'local sColor') outside the if/else statement or as a global variable. I didn't know that local variables inside if/else statements could only be used inside these statements.

addButton(1, 5, 9, 3, 'color', defaultColors[9], 2)...
function addButton(id, decrement, increment, y, type, color, value)
registeredButtons[id] = {}
registeredButtons[id]['minX'] = decrement
registeredButtons[id]['maxX'] = increment
registeredButtons[id]['y'] = y
registeredButtons[id]['type'] = type
registeredButtons[id]['btn_color'] = color
registeredButtons[id]['value'] = value
end
...local bColor = defaultColors[data.btn_color]
You end up with nil, since defaultColors[ 256 ] doesn't exist. From the first snippet, change it to simply '9', not defaultColors[ 9 ] or change the last snippet to just data.btn_color.
If you didn't already know, that particular error means a term function that expected a number didn't get one - culprits are commonly term.setCursorPos and term.setBackgroundColor.
Yap. That was the other problem. Thank you very much to both of you for your help!
