Hi!

How can I count the unique numbers in a range where I have numbers, blank
cells and text, everytime a condition is met?
It's like this:

Source page

Supplier Nº Date
28000 01-01-2007
28001 01-01-2007
jtrjkfff 01-01-2007
28000 01-01-2007
28001 02-01-2007
(blank) 02-01-2007
ddfgdr 02-01-2007
28001 02-01-2007

Results page

Date Count of Suppliers
01-01-2007 2
02-01-2007 1
....

Thanks a lot!
