Clear Fields on Submit

Hi, I love the flexibility of this plugin, but I have one major problem — I’m using the multi-step forms to store data from form fields into session variables. This works great, but the problem is, I need to go back to that form and fill it out again with clear fields and use the same input ID’s. Problem is, every time I go back to the page, the fields are stored from the previous submission. Is there an easy way to do this within the plugin, or do I have to use JavaScript or JQuery? Is this a caching issue? I notice that fields stay filled in even after the session expires — can you tell me where these variables are being stored, if there isn’t a way to clear them? Thank you for any help!
