smoothing elevator

i have an elevator script that goes down when triggered, it works fine, except, when the object lowers, it acts like this, :

the elevator moves smoothly, but the player falls, hits the elevator floor, elevator continues to move down, player falls again.

It gives the appearance of a jittery elevator. Any idea on how to smooth this?

Either apply more gravity to the player, all the time, or parent the character to the elevator when he or she is in there.

you should write some code to move the player with the elevator yourself or make the elevator the parent of the character when it should move with the elevator. if you told that what you used for the character, it would be easier to answer. character controler? rigidbody?
