Hi Jaan, Try this...

1. Add the following formula to cell T4 in worksheet "MPSPLAN.xls" sheet
"MPS"; =Sum(j4:S4)
Copy it all the way to cell T349.

2. Give the spreadsheet range [MPSPLAN.xls]MPS!$D$4:$T$349 a name, say
"Table" using the following commands;

Insert/ Name/ Define

3. Your formula can be replaced by the following;
=VLOOKUP(F$2;Table;17;FALSE)

How it helps.

Is there another solution?
