IF formula: If item from list in adjacent cell is picked, a certain value is inserted

Hi! I am having trouble with this formula. I have a data validation drop down list in one cell that has the following choices:

Not contacted yet
Contacted: awaiting answer
Meeting has been set up
Converted into New Affiliate!
Contacted: Not interested

Next to that, I want a value listed for each choice so that i can do a pie chart. The values would be:

Not contacted yet- 0
Contacted: awaiting answer- 10
Meeting has been set up- 20
Converted into New Affiliate!- 30
Contacted: Not interested- 5

This is the formula I came up with, but it's not working. What do you guys think?


=IF((OR(C3>="Not contacted yet", "Contacted: awaiting answer","Meeting has been set up","Converted into New Affiliate!", "Contacted: Not interested")), "0", "10","20","30","5"))))

Thanks for replying! Unfortunately, that just populates the cell with a copy of the adjacent cell.

Oh, you're right! I'm sorry, I pasted it in the wrong place. You are a genius! Thank you!!!
