Typically you can check the field text for a known html entity to see if it contains html or 
not. I think LC uses "<p>" because almost all html includes a paragraph mark.

if "<p>" is in field "mainText" then -- htmltext is there

If your html doesn't have paragraph entities then see if you can find one that you know will be 
there.

As an aside, I first thought that this would work:

   if the htmltext of field "mainText" <> the text of field "mainText" then -- plain text is in 
the field

which does return "false" correctly. But when I set the text of the field to the htmltext of 
the field and run the same test, it also returns "false". I'm not sure why.
