unhilite line in list field

[betypaul]

Hi
My script has a list field where each selection is utilized in turn.
I would like the selection to be unhilited in turn after it is utilized,
so that as the repeats are worked through the highlights turn off.
Possible?
This doesn't work --

repeat for each line mychoice in the selectedText of fld "mylistfield"
	doSomething
	unhilite mychoice of the selectedText of fld "mylistfield"  -- ?????
end repeat

but, has anyone  found a way to do this?

Seasons greetings to you all

Paul
