hi is there a way for my members to change there pass words or do i have to do it for them and if there is can i get a code so i can add it to my site?
OK, this is an html query not a service query so you are telling us that you either hand coded the function or uploaded a third party script to the server rather than used Bravenet's Password Gate.
However, you have given us no clues about what software you did use.
