Small OsCommerce Text Modification

OsCommerce Modification. Need to change the text at the top of the manufacturers products page, and the text on the checkout success page. Manufacturer Product Page -- Text to be changed From: "Lets See What We Have Here." To: "Click On Video Image For In-Depth Description Of Each Training Video." Order Success Page -- Change the text located where the date the product will be delivered from: "2-4 days" To: "7-10 days" Note: Do not modify any other part of the order success page. There is affiliate tracking code located in the page, and this cannot be modified. So, please be careful. This must be done this afternoon/evening. Looking forward to hearing from you. Sincerely, Paul
