Macros will drive you nuts, because they look for all the world like
regular programming functions that you may encounter in any programming
language. But they're not.
Since you're willing to make changes to the actual macro code, I can pass
on my "trick" I've used in javascript macros. If memory serves, what I've
done in similar situations is to make input and output variables in the
calling environment. E.g.
<$set indate={{!!bestbefore}}.> ...
<$set outval="unused"> ...
Then inside the javascript macro, fetch the value like:
var indate = this.getVariable("indate") ;
and after passing this to the program, return the value like:
this.setVariable("outval",whatever_the_return_variable_is) ;
Then (still inside the <$set>...</$set> tags) use the "outval" result in
your reveal widget.
I don't know for sure if this will work for you, but it's the kind of thing
that I've used in the past.
Remember to back up your TW before messing with javascript macros (since a
crash can lock you out) and that you have refresh your TW before javascript
macros will take effect.
Good luck!
