Please don't say it's just "a dump of a bunch of code"; it has taken me a lot of work and effort. Could you be more kind please? I understand you must have a lot of work and you will have to read a lot of stupid questions but just say "Please post a smaller example" and I will be happy to do it.

Anyway, I will do what you suggest: I'll post a smaller example on another thread.

"dump" meaning "to drop off" not "dump" meaning "where trash goes". The word "dump" used this way does not imply anything about the quality of your code.
