Lookup Values from three different columns in a table matrix

Hello All
I am using Excel 2010 and have the problem as shown in the attached file.

There are 3 Sheets Report, EmpName,Target

Range Names - EmpName, EmpTable,MonthHeader,YearHeader

I am trying to look up for Targets for each Year against each Employee Name entered in Cell B2 in the Report Sheet

I tried the formula which gives the #REF Error

=VLOOKUP($B$2,EmpTable,INDEX(EmpTable,MATCH(A7,MonthHeader,0),MATCH($D$6,YearHeader,0)))

Can anyone guide me with this problem?

Thanks in advance.
