you're letting the user create "html" text. In other words text which contains html markup - specifically it uses html markup to change fonts, colors and so on.
but clarion reports don't have an HTML control, so when you put tht field onto a report you get, well, just text.
clarion reports do support RTF (rich text format) - but there's no RTF editing control for the web form.
So the only solution is to convert the HTML the user submitted to RTF, and then use it on an RTF control on the report. This is not completely trivial to do, and there's no built-in mechanism to do it - but libraries and DLL's for converting from HTML to RTF do exist.
Note however that HTML and RTF are different formats, so you may not get an exact match when you convert.
