Hi Dave,

You're probably better off working with the
'hilitedLine' property of the field - as for not
allowing the user to select certain lines, turn on the
'autoHilite' property and try something like this in
the field script:

##
local sPrevHilitedLine

on selectionChanged
  if the hilitedLine of me is 7 then
    beep
    set the hilitedLine of me to sPrevHilitedLine
  else put the hilitedLine of me into sPrevHilitedLine
end selectionChanged
##

With this script, the user can select any line but the
seventh. Naturally you can make up a custom property
to hold the non-hilitable lines, modify the script to
compare the hilitedLine to the contents of that custom
property, and place the modified script in the stack
script.

Hope this helped,

Jan Schenkel.
