=MAX(IF((Name="Jon")*(Category=B"),Spend))

etc.

which is an array formula, it should be committed with Ctrl-Shift-Enter, not
just Enter.
Excel will automatically enclose the formula in braces (curly brackets), do
not try to do this manually.
When editing the formula, it must again be array-entered.

...
this is now solved.
Another question however,

in a similar manner is there a way to find the maximum, minimum and
average
numbers within the identified fields.
e.g.
Max.....of (--(Name="Jon"),--(Category=B"),Spend)

thanks

I've created a formula

=SUMPRODUCT(--(Name="Jon"),--(Category=B"),Spend)

which sums the spend when columns name = Jon and category = B.

I've now changed the "Spend" array to "SpendVol" array (which represents
a
new column)
therefore use
=SUMPRODUCT(--(Name="Jon"),--(Category=B"),SpendVol)
But this returns #VALUE.

This makes no sense as its the same formula just accessing a different
column.

Does anyone know why this would return this value or if there are any
bugs
that can occur in a file that would cause this.

Thanks
