What type of data do you have in column C? Is it text or numeric?

If it's text, try this:

Entered as an array using the key combination of CTRL,SHIFT,ENTER (not just
ENTER):

=INDEX(Sheet2!C1:C35,MATCH(1,(L12=Sheet2!A1:A35)* (L12<=Sheet2!B1:B35),0))

If the data in column C is numeric and there will be only one instance that
meets the criteria you can use this (normally entered):

=SUMPRODUCT(--(L12=Sheet2!A1:A35),--(L12<=Sheet2!B1:B35),Sheet2!C1:C35)

I need help, please. I have written a formula, which returns a number in
cell
L12. When my formula returns a number, I need to reference a chart. There
are
35 cells in column a, 35 in column B and 35 in column C of my chart on
Sheet
2. If the value in L12 is greater than or equal to the value of column a
AND
less than or equal to the value of Coulmn B same row, then I need to copy
the
value of Column C (same row) into cell L13. Please advise! Is this
possible?!

Best, kris
