Debugging tip: try minimizing the script to hold no code at all. Still
the error? No? Then readd half of the script. Still no error? Continue
until you find the change that yields the error. Repost, when you know
what's wrong but not why, unless you figure that out too in the
process.

Divide and conquer: nails'em every time! Or half of the time. Maybe
once in three? (...four?)
