Adding security questions

Hello everbody,

I try to add my 3 security questions for my apple-ID.

I went to the appleid.apple.com site. I logged in with my appleid and went to "manage security" but there is always only ONE security question, never 3 as it should be.

I tried with Internet Explorer 8, Internet Explorer 9, Firefox 15 under Windows7, and with Safari with my iPad, and always only get the ONE security question that I have set up years ago. I DO KNOW the answer to that question, so there is no problem, but I like to set up with 2 ADDITIONAL questions so i can use the iTunes store again.

I want to add those ADDITIONAL questions with my browser and not use the the iTunes app on my iphone or my ipad, because I want to set up my own questions and not have to use the boiler-plate questions that we get when adding questions by using the iTunes app.

Is there a way how to mange THREE security questions with a normal internet browser under windows 7?
