Auto translate the form based on the website translator

One of my old websites used Google Translator to change text from English to German, and I have seen a Jotform on that website also get translated.  That was some time ago and I have been unable to reproduce this on current websites. Could it be that embedded Jotforms can only be translated by Google if they are embedded in a certain way (iframe, etc.)?  The form is being placed in Adobe Muse in an English/German wedding website.

On this RSVP page, clicking on the little German flag at the top will translate the static text, but not the contact form text.

Any ideas?

The form is not part of your website and it's embedded using our default embed so it's impossible to translate it with your current translator. 

You will need to embed the form using the source codes: https://www.jotform.com/help/104-How-to-get-the-Full-Source-Code-of-your-Form or translate it using our translator tool.
