Displaying name of cell if cell next to it fullfills criterion

[pvp]

Hello,

I have a problem.
I show in one column the maximum selling price one finds
in the row which displays several sales prices.
The selling prices are offered by different entities.
The name of the entity offering a selling price is placed in the cell
to the right of the cell showing the selling price offered.

At the end of the row I have a cell which which gives me the maximum selling price.
Situated to the right of this cell I would like to find the name of the Selling entity
with the highest selling price one finds in the respective row.

Can someone help.

I attached an excel showing my query.
