You need the wikify widget. It's express purpose is to parse wiki text and
store it's output for use elsewhere inside it. So in this example, you
would want the following
<$wikify name="caption" text="{{myConfig##Tag}}-Course348">
<$button>
<$action-sendmessage $message="tm-new-tiddler"
title={{myConfig##Name}} tags={{myConfig##Tag}} caption=<<caption>>
page={{myConfig##Page}} text=<<content "SlideContents">>/>
New Slide
</$button>
</$wikify>
