I cloned your form: http://www.jotformpro.com/form/42945157626967, and I did not have any issues with it:
What issue are you experiencing? Is not saving? Is there any specific feature of the Form Designer that is not working? Is this happening only on a specific browser?
I would suggest you to clone your form and see if it presents the same issues as in the original form.
