Ok -- to learn a LOT about how page text vars behave, you could look at

http://similepedia.com/index.php/Site/LocalTemplates

There is a LOT of page text var play there.  Enough to write a  
dissertation on ;)

I think that you want Group/PageName{$var}.  If you're getting Group/ 
PageName from a variable (which is what I'm doing a lot on Site/ 
LocalTemplates noted above) then the syntax is {{{$Group}/{$PageName}} 
{$var}} I think.  I haven't tried that one.

{*$var} is for use in included pages.
on Group/GroupHeader for example, you would use the {*$var} format to  
use the page variable $var of the DISPLAYED page.  Otherwise {$var}  
would be the $var value from the Group/GroupHeader page.

Did that help?
