Excel 2007 : Help to Auto-fill price on invoice spreadsheet

Hi,

I have an invoice that I use and I want to make it so that when I type in the name of an item that it would first auto-fill the name of the design after I start typing a few letters and then auto fill the price of the item.

I have looked at a few examples in this forum so I have created a "sheet2" and made two colums "Design Name" and "Price" but I have no idea what to do to "link" this sheet up with the invoice. Because when I type in the name of the design in the invoice, the price is not auto-filling.

I'm stumped. I google EVERYTHING and I can't find the answer to this anywhere. The closest I've found is on this forum but after following the
instructions on a couple of posts I'm still unsuccessful. and its really bugging me and hope someone can provide me with some assistance.

I've attached a copy of my invoice (of course I have omitted the private info)
