Hi Steve
Untested, but try this:
<!--set bg color of all slides in show -->
<$list filter="[tag<slidetag>!sort<slidenum>]">
<$vars slidenum={{!!slidenum}}>
<$wikify name="rgb" text=<<bgcolor>>>
<$action-setfield background-color=<<rgb>>/>
</$wikify>
</$vars>
</$list>
Given that you’ve got a transclusion in the variable ‘bgcolor’, the wikify
widget is simply rendering that transclusion, ie converting it into the
underlying value.
Best wishes
Jeremy.
