Basic 13
easiest way to solve this challenge is to do a search or just view the source of almost any webpage to see what a form that posts to another page looks like
then save and edit the page so u can choose the name you want and also when you hit submit it posts to the right url
u can use javascript:forms. like i did and i have an article that talks about that on this site
ill be a little more specific then see the newsletter button on the right side of this site saying "subscribe"
using firefox select some text above and below that button (click and drag the mouse, reason: if u click the button u dont select it..)
with the text selected right click on it and choose "View Selection Source"
now compare that function with the one you are working on and see if it helps.
