thomaskleczka You don't provide much in the way of details. I am assume that by "scrolling text box" you mean a section break field. If so, you can place html code directly in your description text. You can insert html into most fields in a Machform, so this will probably work even if you are not referring to a section break. Try this html:
<a href="http://www.mywebsite.com" target="_blank">TERMS</a>
(I really should have made you Google for the code, but I'm feeling generous today.
