Q: Multiple row-multiple column table lookup

[MarinM]

From a table (Sheet1) I want to fetch data based on two columns and three rows using formulas or VBA that checks until the first empty row or first empty column. Criteria is in rows 1:3 and columns A:B. There is always only one combination for certain parameters, e.g. Jack, 01.01.96-31.12.96, 1 (column A) and 6 (Column B) appears only once and at intersection of it is number 2.

Excel Workbook

Sheet1

What do I have to do in order to get output in column C on Sheet2 based on cells B1:B3 Sheet2 and A5:B24 on Sheet2?
For Sheet1 and given input on Sheet2, output in column C Sheet2 should look like in the picture:
