Greeting,

I have two columns, E&D. E has a material number and D has the size. There
is more than one size for one material. What I want to do is count the number
of size base one size and material. For example:
Material# size
1 1€�
2 2€�
2 1€�
1 3€�
2 1€�
3 4€�


Summary:
Material # size count
1 1€� 1
2 1€� 2

Thanks
