Microsoft Excel? Problem

Anyone here who has mastered the art of the famous microsoft Excel? Probably the most common business tool.

I'm trying to create a nested loops, or you can say- trying to fix too many formulas into 1 cel.

I want to find the value of a specific cell- but it has to match atleast 3 conditions or 4 in some cases.

I'm trying to work with the following formulas.

Vlook, hlook, Index, and Match.

Does anyone know of any other formulas, or functions that can help me find a particular value from an excel- worksheet database- which must satisfy atleast 3-4 conditions.

Thanks.
