Adding Text and a Field value to the $Body of a workflow post

In my prior question, Armand helped me to write a Workflow rule that would automatically post the value of a text field to the Discussion thread.  I'm trying to figure out the right syntax so that the post would start with the text "Brief Status" so that the posts could be filtered later, along with the actual value of the Brief Status text field.  What would the syntax be?  I've tried to use:

"Brief Status", $C_BriefStatus

But that doesn't work.  How can I essentially concatenate my own text with the value from the text field?

Thanks!
