Could Anyone Please Guide Me ?

Hello ,
I am new to this arena.
Today as I logged in I got this message "In anticipation of your first sale please click the link below and provide us with your paypal adress so that there are no delays processing your payments. if you dont have an account with paypal its a free one to setup .just click http://paypal.com

Update payment information.

I updated the details but I dont get to see anything sold in my sale section :( please help
