How to make an invite all friedns button?

I just made my first fb page ever!
I made it with the FBML code where the user needs to complete
4 steps to get something.
The problem that i have is that on step 2 when it:
invite all friend
When i click on it, it does not open a box for me to invite my friends,
what it does is just opening step number 3.
How can i change that?
I want to have a live "invite all friends" link and only after they do that,
step number 3 will be revealed.
Anyone can tell me how?

Maybe i also did something wrong with the page id.
I had to copy the page id to the FBML code twice, but the problem
is that i dont really know where the page id starts or ends.
It goes something like this:
/10#############?v=app_49###########&ref
I only copied this part: 49###########
Was that the right thing to do?

No FB experts that can help?

Sorry for bumping it but i really need your help
I am stuck with my fan page because of this

fb stopped the invite code from fbml tabs a while back i think you might find your script is out of date

Agreed. Also, even if you get this working, do not expect your fan page to last more than 24 hours.
