Please refer to the forum rules (http://www.codingforums.com/rules.htm), specifically this one:1.5) No homework assignments - Do not post your entire homework assignment and request that other members do it for you. This is considered cheating, and your thread may even be used by your school to prove your guilt. Now, you may ask for advice or help on a specific aspect of your assignment that you're having trouble with. Use common sense as far as what's acceptable in terms of soliciting help with homework assignments.

You can use AJAX to check if the current password is correct before enabling the 2 new password text boxes.

Also, why do you need a "Don't know password?" link?. If they don't know their password, how did they log in in the first place to get to the change password form :rolleyes:?

Normally you would have a "Don't know password?" link on the login page.

Should we ask your professor there in Sri Lanka if it's okay if somebody else writes the code for your homework assignment?

Besides being unethical as vinyl-junkie already pointed out it is a violation of the rules here at Coding Forums to ask that somebody else do your homework assignment for you.

Sorry For the violation rules.....
