error CS1525: Unexpected symbol `float'

So I was following a YouTube tutorial for a game i’m making and atm i’m doing prallaxing. I copied the code word for word and I am still getting the error.

NOTE - I HAVE NEVER CODED C# BEFORE AND THIS IS MY FIRST GAME

Please Help

Please dont put your code on a picutre just paste it in using the Code Sample on the toolbar where you can make your text bold

but try changing
background[1].position = Vector3.Lerp (backgrounds[1].position, backgroundTargetPos, smoothing * Time.deltaTime);
to

background[1].position = Vector3.Lerp (backgrounds[1].position, backgroundTargetPos, smoothing) * Time.deltaTime;
