=SUMPRODUCT(--(A2:A10="Adam"),--(C2:C10<""),B2:B10)

replace "Adam" with a cell reference and then change the name in the cell,
this assumes that empty cells (in date range) are not paid and non empty
paid

I have an invoice & payments tracker for sub-contractors, im trying to
create
a formula which will allow me to calculate how much each contractor is
owed.

For each job, the subbie is allocated a proportion of the total invoice,
and
gets paid when the client pays

At the moment I have something like this:

Subbie Subbies commission Date Client Paid
Adam 100
John 200 1/09/2005
John 50
Adam 300 5/09/2005
John 100

I need a formula to add all of Adams commissions which have NOT been paid
by the client, ie = 100

Then another formula to add all of Johns commissions which have NOT been
paid by the client, ie = 150

Im sure its really simple, Ive been trying to figure it out but keep
getting #VALUE errors

Thanks heaps!
