Excel 2007 : Finding a value based on 4 criteria

I could use VBA for this, but I would prefer not to (because the next guy can't update the file)

I have a project where I need to track time.

Time is based on four criteria
Username
Project ID
Phase ID
Date


I've been messing around with vlookup, index, and match, but can't get them to work. I'm sure someone has done this.

I would appreciate the help. Thanks.

I've attached an example.

P.S. all i need is the basic structure of the equation/script
