Unable to Pass to the Next Page

A person within my association at a different location than the one I'm at is having trouble advancing past the "Sunscreen and Administration of Medication" page of our jotform.  I have not been able to recreate this on my machine, however.  They claim no error shows or anything like that.  They say they just click next and nothing happens.  Any idea what could be going on here?  

I just tested your form, and I was able to pass that page. Probably, it is a browsers cache issue. Please ask the user to clear his browsers cache, or try using a different browser.
