Thank you for your quick response!
Sorry for being such a dunce, but I have never made any changes to the parameters of a module using the text area. I'm fairly conversant with css and html using the sheets, and have some limited experience with php, however I'm not quite sure how to work with the paramater text fields. I'm really more of an administrator than I am a coder.
For example - how and where would I add the html to generate the divs in this code block?
Code:
{p[cb:userfield field="avatar" reason="list" /]} added a new guestbook entry to {r[cb:userfield field="formatname" reason="list" /]} - {e[date]}
Also, is there a tutorial somewhere that would help me learn how to work with these text fields?
