Answer
Hello,

I need a little more clarity please. When you are refering to the floor shift or the indicator on the dash?

This is a 20 year old car and if I remember right it has both.

If it is on the floor shifter, it is probably a linkage cable that is worn out and stretched and you need a new cable.

If you are refering to a dash indicator the adjusting clip came loose and needs readjusted. My bet is on a bad shift cable though because it was a common problem.
