Show only customers who purchased all selected values (brands)

[#1]

Hello,

Hope someone can help me. What I want is this: to get a list of customers who purchased all selected Brands. Now, when I select three brands like Bison, Altrex and AXA I get all customers which purchased one or more brands, See below:

Brand	Customer
Total		905
Bison	Retail	235
Bison	Philips	202
Bison	Organised Deal	155
Bison	Not Organised Deal	170
Altrex	Retail	55
Altrex	Philips	35
Altrex	Dos Pinos	25
AXA	Retail	16
AXA	Philips	12

What I want to see is this:

Brand	Customer
Total		555
Bison	Retail	235
Bison	Philips	202
Altrex	Retail	55
Altrex	Philips	35
AXA	Retail	16
AXA	Philips	12

I think I need to use set analysis, but I just can't figure out how. Thank you in advance.
