try using an Array function (Excel Help is good for this - you could
also load the 'Conditional Sum Wizard' Add-In from the Tools menu to
help you write the formula )

something like

=COUNT(if((B1:B103)*(J1:J10<1),B1:B10))

Where * represents AND & + represents OR

Can also replace COUNT with SUM if required.

(note : you need to press and hold Ctrl+Shift when pressing Enter after
typing the formula - this tells Excel that this is an Array Function.

(make sure your ranges match; aviod referencing whole columns as doing
this multiple times will place strain on Excels calculation cycle
(noticeable on my laptop when using around 50 of these in a workbook))

hope this helps Jones
