Thanx for your solution.  Now I have to face another issue.  The "pollID
$pollID" elements that were joined together into one element in the same
list now have to be broken apart within the same list.  How do I do that
too?

Thanx
Phil

Your problem is that pollID and 2 are each elements of your list.  If
you want them to be treated as one element, you need to quote them.
lsearch only searches individual elements.  If you want to find the
particular element of the list that precedes the numeral "2", you'll
have to loop over the elements.  Perhaps you would be better off
quoting the two strings to create one element, e.g. "pollID 2", when
you create the list, instead of when you search it.
