Okay, I've tried to find answers by reading every page I could find, but I'm still not understanding.

Let's just say:

I have a user page called "Raquel". That page calls a template called "Userpage. So far, so good.

Now I want to create variables which will be substituted on the user page, and that's where it's falling apart.

Let's say I want the city where "Raquel" lives to be substituted into her page and the city where "Pamela" lives to be substituted into her page.

I thought that defining the variables in the user page would do it, in Raquels page: <ff> city = Paris </ff> and then in Pamela's page: <ff> city = London </ff>

In the template file I'm using: City: {{$city}}

But, it's not working.
