You will need to be a little more specific as to what the problem is. It would be quite a chore reading through that code looking for unknown errors.

Actually I don''t usually preview my posts (that''s why they''re so incoherent), but if I was posting this much code (somebody slap me if I do) then I would.

in response to Ahmed Saleh:

The problem with your code is that it''s too long. Try to find out where the error you must have (otherwise why would you post?) is, and only post that portion. Then people will be more willing to look it over for you.

Or read your other thread on this forum where I told you what the problem was... lol

But next time ATLEAST use code formatting in your post otherwise I''m not gonna even try... lol

Thankes All Brother very very Thanks
i''m Solve my Proplem Thanks All agin
