Lookup on Duplicate Values

Hi All

I'm looking to return a lookup value based on a set of data that has duplicate values. Attached is the a file that contains the issue I am facing. The end result that I am looking for is from Cell I3 to L3. What I need is a formula that looks up at Cell C2 within the data range of E3:F19 and the results should be in I3 to L3. Cell C2 has to be in months. Appreciate your assistance on this.

Best regards
