I wouldn't know, sorry.

But, I think that YOU, being a member of this forum for 2 years, should have learnt how to use [code] tags which make your code easier to read.

Nice code tags! However, your code is still unformatted and difficult to read.

Yes, I agree, I'm useless - the fact is, I never did that. I'm just trying to make it easier for other people who might know how to help, so that they wouldn't need to read your unreadable code.
