Thank you c pa! The problem with this attempt is that *sort-field* is assigned to *in* TableHeaders(). This can't be done elsewhere because of *currentField* being rendered inside TableHeaders. Or am I wrong?
I think, I misunderstand some basic concept about the variable assignment: \define TableHeaders() <$list filter="[is[current]split:table-headers[,]]" variable="currentField" ><th><$button class="tc-btn-invisible" set="!!sort-field" >setTo=<<lowerSortField text="<<currentField>>">> ><<currentField>></$button></th></$list> \end \define lower(text) @@text-transform: lowercase;$text$@@ \end \define lowerSortField(text) <<lower $text$>> \end I want lowerSortField() to return the evaluated string. With the code above I get *true. *Perhaps my macro-nesting is defective? When I try to transmit the <<currentField>> in a way similar to c pa's proposition by wrapping it in a setWidget, i.e. \define TableHeaders() <$list filter="[is[current]split:table-headers[,]]" variable="currentField" ><th><$set name="currentFieldSet" value=<<currentField>> ><$button class= "tc-btn-invisible" set="!!sort-field" setTo=<<lowerSortField>> ><< currentField>></$button></$set></th></$list> \end \define lower(text) @@text-transform: lowercase;$text$@@ \end \define lowerSortField() <<lower $(currentFieldSet)$>> \end I get *<<lower a>> *where *a* is the the *currentField* value. I'll be much obliged for any further help. jim Am Freitag, 12.
