Help!

EDIT - I figured it out. Nevermind.

Can someone help with this? I don't understand why the 'x' variable is undefined. Any help would be greatly appreciated

I think your issue is the evaluation equal sign at the end of the function definition,

Get rid of that and see if it helps.

(BTW, what are the definitions of p and wDL?

Can you post the sheet?
