Formula for correlating cells based on a drop down

I have a dropdown list (C1 on the dashboard sheet). When January is chosen in that list I want the value in D15 on the dashboard sheet to match the value in B13 on the Target sheet...and then the same for D16 on the dashboard sheet and B13 on the Actual Sheet. When February is chosen the values should match for the month and so on.

Essentially I want the drop down list selection to populate the right numbers based on the month chosen. Let me know if i am not making sense.

thank you for any help!
