Calendly code won't work - when I enter it says 'code removed'

Hi there, 

I am trying to add my calendly widget to my site. When I add the code it just says 'code removed'. I've followed all the steps and YT videos. Some talk about adding a code injecting via settings > advanced but when I go to do that it won't let me - is it a premium feature? Is adding calendly a premium feature? I didn't think it was. 

Thanks,

Charlotte

Adding javascript is a premium feature and requires a business plan.
