Answer 1

Click the little + icon to the right of the field where you're entering the IP address. That will open a second textbox that you can use for the second value.

Answer 2

I noticed in your screenshot

That you have @-------------.com (where I assume ----------- is your URL). You don't want that. You want simply @ there (and www if you want to redirect www.--------.com as well). @ means "this domain name", which in your case is ----------

Hope this helps!
