How to find a result when you need to search a number of columns

I have a problem that I am sure a formula will fix for me but I just cant seem to work it out, I need to search multiple columns to find a match before I want the result selected which itself will be in a different column.

It seems to me to be an extension of the VLookup function. Attached is an example of the sort of spread sheet I am trying to pull data from. I am trying to get the result of Area 5G, for site ZZ, KPI 2.1, Date Apr-13. As well as the result for Area 5G, Site (empty), KPI 2.1, Date May-13. I hope this is not to convoluted and someone can assist.

Thanks
