Blanc Form problem!

Hi, I am building a 2 part form on my landing page. It works when u do it in one go but if you forget to fill in the first part and then get to the second and click it away. The when trying to get back to the form it loads the form but with a blanc page. it is there because your mouse and browser allows you to enter it but you just are not able to see it. I have been breaking my head on this the last couple of days? Anybody have any ideas?

Kind regards
