Hi

I have a spreadsheet withthe following data:

28/08/2008 09/05/2008 HINGE SA28566 8 £1.10 £0.77 £6.16
20/08/2008 28/08/2008 HINGE SA28389 24 £1.10 £0.77 £18.48
14/08/2008 21/08/2008 HINGE SA28268 12 £0.00 £0.00

What I need to see is the total number of units, of which XXX are Free
of Charge between xxxx date

Sorry, but I am struggling and got so far =COUNTIF(J2:J924,"£0.00")
