Which browser you are using? I tested you page inside of Firefox, Chrome and IE8 and it seems that it is working. I do not facing issues you are mentioning.
I took a look at your jotform and as mentioned by bkljaic, I am not able to recreate the issue.
This leads me to believe that the issue might be happening for you on the jotform after embedding it on your website.
Could you please let us know if that is the case and give us the link to the page on your website where the jotform is embedded?
