Create a list according what i choose in A1!

Hi all.

I need your help on this.

In A1 of the first sheet i choose a customer. In column D of this sheet i need to see ALL the products that this customer works.

IN the priceList sheet i have in column A the Customers Names.

Starting from B1 and in the next columns i have my Product Names.

From b2 and down and for all the columns to the right i have the prices for eatch customer for eatch product.

If one customer does not use any product then the cell is blank.

I believe that looking in my example sheet everything will be clear for you.

Thanks in advance for any advice.
