Adding another page in excel spreadsheet

I have a bid form that has two pages, first page has data for the bid and second page has exclusions and sums up the first page, I want to insert another page identical to page one, and make it a 3 page form so I can add more data, the first page sometimes is not large enough to fit all bid inclusions in. If I use copy or insert page it inserts both pages and I only wish to insert or copy page one, any help???
