Using tabs and validate

Using tabs and validate

I am a relative new user to jQuery so be gentle with me

I am trying to combine the tabs plugin with the validate plugin. What I have is a page with 3 tabs. The first tab contains registration information that I need the user to complete before he/she moves on to tabs 2 and 3.  Now I am using the validation plugin to validate the information on tab 1 and this is working out great. However my problem is that the user can still click on tab 2 or tab 3 before the information on tab 1 is complete. So what I need is a method that will either prevent the user from clicking on tabs 2 and 3 unless the information on tab1 is complete.

If anyone has a example of something like this in action I would be most grateful
