Hi Ardus,
I think the SUMPRODUCT could be dangerous - if there is more than on
match they'll be summed, whereas INDEX/MATCH would find the first matc
only. Also should be
=INDEX(C1:C99,MATCH(1,(A1:A99="crit1")*(B1:B99="cr it2"),0))
needs to be confirmed with CTRL+SHIFT+ENTER
Other options would be to use another column to concatenate and the
just use a VLOOKUP or INDEX/MATCH to lookup concatenate
value.....or...
=LOOKUP(2,1/((A1:A99="crit1")*(B1:B99="cr it2")),C1:C99)
which gives the last match if more than one...
