HELP! For "Fading Grid"!

Can anyone tell me why the “Fading Grid” tutorial wouldn’t work if I only copy/paste the codes there?

Since it was based on the “Grid” tutorial, am I supose to go through --copy/paste-- that one first?

Also, I’m very confused when it says: “[SIZE=2][COLOR=black]Select the movieclip, and give it the instance name image (in the Properties Panel, on the left right under the dropdown box).”

Am I not supose to write “image_mc” rather just “image” for the instance?

:d:
