LOOKUP FUNCTION WITH SUMS ABILITY

Hello,

There might be a simple answer here but either way I need help, let me
explain my problem. For example "SHEET1" has granny smith apples in A1,
"SHEET2" has granny smith apples located in A:A (more than one entry) and
price per granny smith apple in B:B. So an example might be granny smith -
10p or on another row the granny smith apple might be 15p, now what I need
from sheet1 is the total value of granny smith apples. So I guess I require
a lookup function that sums values, is this process possible?

Any help or advice would be greatly appreciated.

Regards,
James.

You could use:
=SUMIF(A:A,"granny smith",B:B)

SUMIF() did it for me. With "Granny Smith" in Sheet1!A1, a series of
different apple names in Sheet2!A1:A10, and apple prices in
Sheet2!B1:B10 the formula on Sheet1!B1 is
=SUMIF(Sheet2!A1:A10,A1,Sheet2!B1:B10)
