Need some small Excell help

Hi all,
I hope someone can help me with my problem

First, look at the attached image
It's a small automation-program I'm working on.
After each Product number, theirs the amount of that product that a person has bought.

I want to create a new sheet where I can see all the orders personID 25 has made,
it should only have two columns,
The first one that shows all the prodnr's that personID 25 has ordered and the second one shows the amount of that prodnr(how many times it was purchased by this person), prodnr's with a zero should be ignored.

I was trying to do this with some matrix-formulas but I just can't get it to work, maybe somebody here can help me...
thx
