Pre-select / highlight list field lines on cardOpen?

I’m using the selected lines of a list field as a simple filter. However, when I navigate from the card & return, the selected lines are forgotten - so the filter has to be reset manually.

So, I’ve added a script to trap the selections & save to stack-level custom properties, so they’re available on cardOpen...

on mouseUp
   put the selectedText of me into tScheduleFieldSelected
   set the ScheduleFieldSelected of this stack to tScheduleFieldSelected
end mouseUp

… but I’m struggling with errors on the openCard script to set the selected lines... 

on openCard
   // Set the Extract folder
   // Get the CSV files into memory  
   // Get Selected Field
   put the ScheduleFieldSelected of this stack into tScheduleFieldSelected
   repeat for each line tField in field ScheduleFields
      if tField is among the lines of tScheduleFieldSelected then highlight tField
   end repeat
end openCard

LiveCode errors with ...(Handler: can't find handler) near “highlight”...

Is this a simple syntax issue or is it not possible to select / highlight list field lines via code? I can’t find anything in the documentation or Google on forcing selection in lists.  
Thanks & regards,
