So there we have 698 lines of highly technical code with zero useful comments and no specification, and we are supposed to know why it doesn't do what you expect. You may be lucky, but I suspect that you are looking for far too much work from us here.

hi;
can put your log error
i advice you to split your code into some methods and add some comment to make easy debugging process.
;)

thr no error
