Well perhaps you're not doing anything wrong. Looking at what you included below there's a lot of it and I suspect that many people really don't want to wade through loads of code. Wherever possible I try and get a small example of the problem. Often I solve my own problem by trying to make a simplified version of it. The other thing to remember is that people are busy. If you have a problem and it looks like a lot of work to take it up then people may just pass it by. Many Flexcoders may not use the feature you are having a problem with. The last thing to remember is that nobody is obligated to respond to any query, so the simpler the query the more likely it is that you'll get a reply. Lastly, it's just after Christmas and people are no doubt pretty busy after the holidays. so flexcoders may not be their first priority. Generally speaking, flexcoders is pretty helpful, but theres no rule that every query will be answered. Sorry, I'm not going to wade through the example below.
