Help a newbie? - Same title on all prog windows

Hello scripters

I kinda need your help if possible.
I want an auto instalation of a program.
So far i managed to move the cursor and click next in the first page , but the next windows has the same title
Maybe the third page would have the same title and it seems that the WinWaitActive dont work when i use the same title
I read a bit in help files that i could use &handle?
Maybe i bit syntax help

Sorry for noob Questions
