Is it possible to reset/clear a previous page of the form when hitting the Back button?

Hello,

I have a form  - http://form.jotform.me/form/40871089560459

Once the customer has filled in his info,    clicks Next,

They go to a selection page,  if they need a different dimension of the same category,

Then the previous details are still on the page.   

Question,  How can it reset this be blank?   

Our customer may have 30 differnet dimensions of cabindet doors.    If the form is not reset to be blank everytime,  this increases the chance for errors  Tremendously

Please Help,

Thanks

Scott
