SUMPRODUCT is likely to be the best bet.

I have created a worksheet at home on Excel 2007 using 'sumifs' and
'countifs' formulae and when I have saved this (in .xls format) and then
opened it in Excel 2003 in work, it doesn't recognise this formula.

Is there a way of converting this appropriately or an alternative formula
I
can use for sum/count if command with multiple criteria

Thanks
