How do you set up "Immediate payment required" when selling on ebay?

I want Immediate payment when I sell an item on ebay. I have looked on the help page but it was no use to me. Is there any power sellers out there that can give me step by step instructions|||You can only set this up with the buy-it-now feature...here's step by step instructions...go to www.ebay.com and click on sell, then sell an item. Enter in some key words as to what you're selling and click on start selling. when ebay redirects you to the "create your listing" page, scroll all the way to the buttom and click where it says "to see all listing options, switch to the sell your item form now..select your category on the next page and click continue...in the next page, create your listing, and under the "decide how you want to be paid" section, check the box that says "require immediate payment when buyer uses buy it now"...Hope this helps...If it does, please choose best answer so I can get some points :) Thanks
