Hi,
I don't use FET, generally. But I do know data structure. It seems to
me that your difficulty is using the Tag field for everything. What
you want is a field (or slice) like "UsersChoice" that contains the
value the user selects. Surprisingly, I don't see support in FET for
field or slices, but I imagine someone has done it. There is support
for the Data plugin, though if you have fields and slices why not use
them? Anyways, then your FET would be something like:
<<forEachTiddler
where
'tiddler.tags.contains("Tag1")'
script
'function getTiddlerField(tiddler,fieldname) {...code to get
field ...}'
sortIntoGroupsBy
'getTiddlerfield(tiddler,"UsersChoice")'
...
