Embedded jotform in website will show back button

Hello,

your service is excellent and we haven't faced any problem, until some clients told us something was wrong. 

When you enter here http://www.tot-em.com/horizontal the buttons "Atrás" and "Siguiente" appear just a few seconds before they become only one button: "Siguiente". But sometimes, both "Atrás" and "Siguiente" remain there and clicking on "Siguiente" doesn't work. What we need is only one button, "Siguiente".

This happens aproximately the 10 to 20% of the time you load the page, what means a loss of the 10 to 20% of the sales we do...

Hope you find a solution and thanks a lot for your time!

I don't see the same problem in the stand alone version of the form http://www.jotform.com/42776457406968

So, to solve the problem please embed the form using the iFrame version, please remove the current script and be sure you remove the script portion of the iFrame code and that you just paste what it is between the <iFrame> tags.
