Hi David,

I forgot that the 'select' command is a bit quirky at
times. Try this version.

on mouseup
  get the value of the clickLine
  put char 1 to 3 of word 5 of it into tcat
  put 0 into j
  repeat for each line i in me
    add 1 to j
    if i contains tcat then put j & comma after tLines
  end repeat
  if tLines is not empty then delete char -1 of tLines
  set the hilitedLines of me to tLines
end mouseup

Hope this helped,

Jan Schenkel.
