I want to create a button that creates an opportunity with defined fields. This is what I got so far:

 

window.parent.location.href="{!URLFOR($Action.Opportunity.New
,Opportunity.Id, [opp4= Account.Name, opp3="ProductName -  "&Account.Name, opp7= "555", opp9= TEXT(MONTH(Today()+7))&"/"&TEXT(DAY(Today()+7))&"/"&TEXT(YEAR(Today()+7)) , opp11="Qualified Lead",p3="012500000009CJ7"])};"

 

This works. it takes me to the opportunity creation page though with all the fields that are defined filled up, but I have to still click on the create buttons.

 

Is there a way that I can do this and make it automatically create the opportunity and send me to the opportunity page rather than showing me the create form all over again.
