Use "on selectionchanged" in the script of the field!

And you can speed things up a bit with using "the selectedtext of fld xyz"
This will give you a CR separated list of the TEXt of the selected lines :-)

Like this, I dared to shorten it a bit ;-)

on selectionchanged
  put the selectedtext of fld "CropYears" into sYearList
  replace CR with ":::" in sYearList
  answer sYearList
end hiliteChanged
