When I took a look at your jotform, I did find it strange that only text and submit button were there, but looking at the conditions, I was able to see the issue.
This is how it looks:
There are many "This field has been deleted" warnings, which by themselves can cause a lot of issues, while the actions that are there are all stating that you want the fields hidden.
Basically this resulted in all of your fields being hidden.
Once you fix the conditions to match what you are after, the form should look something like this: http://form.jotformpro.com/form/52014262924953
Do let us know if you have any issues setting up or removing the conditions and we would be happy to assist.
