Hi David The first wikify widget in the example below generates a string of HTML code "<h1 class="">My Heading</h1>” which you can see when it is directly displayed by the text widget. When you use the double angle bracket syntax to render it, that HTML string gets wikified a second time, and the <h1> HTML tag is rendered into the equivalent wikitext.
In the case of the second wikify widget, you’re wikifying a text widget that renders the plain text of the variable. Thus, the result stored in the testOutput2 variable is the plain text of the original testVar. Then, when you render it with double angle brackets, it is wikified again, but in inline mode, and so the “!” isn’t recognised as a heading because it is block level.
