=VLOOKUP(C8,'[your_file_name.xls]PRICE'!$D$4:$G$14,3,FALSE)
c8 is the lookup value
[your_file_name.xls]PRICE'!$D$4:$G$14 is the range in the other file to lookup
3 means the data is in the third column
the 1st column is the data your matching it to
and false means exact match
hopr this helps some

heres a hint
write the formula by using the paste function have both workbooks open. Put formula in the book you want then use the refedit box to highlight range for each value, if the range is in another file just select that file while writing formula.
hope this isn't tto confusing
