The answer to this problem will probably be so simple, I’ll slap myself.
Within Webflow, I want to create this scrolling iFrame, with a calendar inside.
The functioning page is here: http://amrca.com/calendar-2019.html
In the Webflow version, I dragged this embed code into appropriate section:<iframe title="Calendar 2019 Content" src="http://www.amrca.com/calendar-2019_content.html" width="535" height="600" style="border: 0; center"
It should work in this Webflow page, because the same code works in the live, non-Webflow version. The full src URL is in the code, but why is this area blank?
Here is the Webflow published page, with missing iFrame content:
And here is the read-only page in Webflow. Please look at the index “home” page, named amrca-membership-form:
Please tell me what I missed. Thank you all so much.
