Return Text based on criteria

Hi All,

I am wondering if you all could help me.

I have a large database which has some other formula in it but I am having trouble in getting either "Primary" or "Secondary" value returned in Column C against each entry of column A "code" if its matches with the same date in a date column B. it would be great if i could have some of your thoughts on it.

OUTLET DATE Primary/ Secondary[/B]
1433079 21/06/2013 Secondary
1431970 01/08/2013 Primary
1431970 01/08/2013 Primary
