As an update to this thread, earlier this year
QB released an easier way to embed links on forms. For URL field types, go to the field settings under "Display" and there is an option to "Embed as iframe in forms."
So for example, you could put your iframe embed code in a code page and then call your code page via a formula - URL:
https://SUBDOMAIN.quickbase.com/db/DBID?a=dbpage&pageID=4
https://SUBDOMAIN.quickbase.com/db/DBID?a=dbpage&pagename=mypage.html
