Setup wordpress for Sub domain?

i jus created a sub domain and wish to install wordpress blog. can anyone help me? i am basically lost.

Have you seen the Goodies>“One-Click Installs” section of the DreamHost web panel before?

Free unique IP and $67 off with promo code [color=#CC0000]FLENSFREEIP67[/color] or use [color=#CC0000]FLENS97[/color] for $97 off. Click here for more options

thanks alot!!!

I’m trying to One-Click install but keep getting message that the domain name must contain a dot–but that is all auto-filled on the one-click. So what am I supposed to do?
I was naming the part I fill in “blog”

Thanks. Got it!
