Subtotal Count Of Help

Hello,

I am trying to get a formula working but have been having difficulities producing the desired results. I am wanting a subtotal formula (so that I can filter) that will give me a # value when Column I has a value of "Win" and Column O has an amount greater than 0. I would also like to have this formula ignore a result when Column O is blank. My data range starts in Row 12 and I plan on making it a dynamic range due to future entries. Any help would be greatly appreciated!

To help better illustrate what I am looking for:

Column I Column O

Win 5
Loss -12
Win 7
Win 8
Win
Loss -1

In this example, I would want my formula to exclude the Win with a blank value in column O, resulting in a desired total of "3" .
