Dear,
I am getting following error on a third party integration in a HTML element in Sitejet website builder ([https://cms.sitejet.io/320733/contact](https://cms.sitejet.io/320733/contact)).
According to the third party in question (10to8) the code seems correct at their side. Could you help me to get it properly embedded.
Google developer error shown:
contact:27 Uncaught TypeError: Cannot read property ‘init’ of undefined
Third party code:
this part is ok →
[See Online Booking Page](https://10to8.com/book/qmqgepvleqpfaulqec/)
this script gives the error →
thanks ahead,
Mark

Hi! I don’t see your website (your url can be acessed only from your partner account), but other users reported in the past similar [issues](https://community.sitejet.io/t/how-to-make-html5-banner-work-on-sitejet/716/10).
If you are looking in the Editor in the Preview mode … the script(in the HTML element) will not run/execute in the Editor.
Preview the page in the **Frontend** (Live/Preview)
