Two forms in Jquery slider validation problem

I am using a jquery slider and in the slider I have two forms. when a user selects form number one, the link will be like this: www.webx.com/form-test.asp#1 and when they select form two the link will be www.webx.com/form-test.asp#2 . So basically the ID in the url changes depending on the form selected. Now I would like to create a jquery or javascript validation depending on what form the user had selected. So if the user selects form one (www.webx.com/form-test.asp#1) the validation only works on form number 1. Form 1 and 2 got different fields as well... Form 1 got txtname and txtsurname and form 2 got txtname, txtsurname, txtaddress... Any help please? THANKS
