Apologies for the messy code and for including the irrelevant bits.

That's exactly what I was trying to do, except that the values for the
variables should come from fields of other tiddlers, and not from the
defining tiddler. At last, I finally got my code working by wrapping the
<$set> definitions in a <$list> filter. My initial conclusion was that if a
variable is <$set> and wrapped in a <$list> filter then its value will not
be available to a macro defined outside of that list -- this is of course
incorrect. It was, again, my own syntax error.
Jeremy, thank you again for your pointers and help. I did not correctly
close the </$set> widgets or just left them open. Also, the
<<currentTiddler>> definitions were reduntant, so I removed them altogether
and got a cleaner code.
Anyway, here's the working code (cleaned up a bit), just for the record. On
button click, the macros calculate a result using fields from tiddlers
listed by the <$list> filter, save that result in a data tiddler, which
then is transcluded next to the button that was clicked. Issue resolved :).
Thank you again Jeremy, PMario and Jed Carty for all your invaluable help
and advice.
\define Updated_status()
<<TrackerStatus $(tracker_start_date)$ $(tracker_end_date)$ $(currentVal)$
$(targetVal)$>>
\end
\define bAction()
<$action-setfield $tiddler="_data000" $index=<<currentTiddler>>
$value=$(Updated_status)$/>
\end
\define Button()
<$button actions=<<bAction>>>
⥁ Status</$button>
\end
<table>
<$list filter="[!days:tracker_start_date[-1]][days:tracker_start_date[0]]
+[tag[tracker]] +[sort[tracker_end_date]]">
<$set name=currentVal value={{!!tracker_current_value}}>
<$set name=targetVal value={{!!tracker_target_value}}>
<$set name=tracker_start_date value={{!!tracker_start_date}}>
<$set name=tracker_end_date value={{!!tracker_end_date}}>
<tr>
<td>
<$link to={{!!title}}><$view field="title"/></$link>
</td>
<td>
<$list filter='[[_data000]getindex<currentTiddler>]'
emptyMessage="@@color:#cecece;(no data)@@"><<currentTiddler>></$list>
</td>
<td>
<<Button>>
</td>
</tr>
</$set>
</$set>
</$set>
</$set>
</$list>
</table>
Best regards,
Hubert
