Can someone solve this following excel sheet?

Note 1: Assume that Telco raises $5 million at a pre-money valuation of $5 million. Suppose that Valhalla invests $2.5 million of the total $5 million raised by Telco (the remaining $2.5 million are invested by Columbia Capital). Note 2: Assume that Telco raises an additional \$5 million, and that Valhalla contributes its pro-rata share (i.e., 25%, or $1.25 million) of these \$5 million. Note that this is consistent with the description in case Exhibit 1 (page 8). Valhalla ownership \%: Note 1: Assume that Telco raises $5 million at a pre-money valuation of $5 million.
