I want to change profile.xxx property. When the member is online.

Question

 hi.

I use login control in my web page.When the user is online I want to change profile.xxx properties but as it does not allow the anonymous  users it says it cannot be changed.

Eventhough  I write the codes in “loggedin” event could you please tell me why I can not succeed  to change the profile xxx properties.

As a result i wanna change the properties of the profile xxx as soon as a user is online.
