How to fix a Compile Error Expected: End of statement.

OK so here is what I am trying to do,

I have the below macro or VBA what ever you call it so that users no where to input text and data in a form and then when they click print it will hide the background color this is the code I am using but it keeps telling me
Compile Error:
Expected: End of statement.

What am I doing wrong?

Private Sub Change background color to Grey for cells listed
