Multiply based on dropdown list conditions.

Hi there,

I am trying to fine tune a labour/crop work tracker. This is what I am trying to accomplish.

1) I would like to have the total labour hours per team member displayed in Q11.
2) I would like to be able to choose a letter from I11's dropdown list, and it selects the appropriate Target Event based on the letter.
3) Now each target event has a different amount of hours located in Column C.
4) Finally I would like the total labour hours from column C multiplied by the # of People in P11 and displayed in Q11.

I need help with the dropdown list part, I need the formula to be able to know where to look.

Here is the file Crop Logs - Template.xlsx

Thanks in advanced.
