using echo inside classes

[xwin]

I'm having a problem using echo from a superclass...

I have index.php, which echo's the output of go() inside class System ($System->go()) in system.php

$System calls $Skin (skin.php) which loads $Skin->output($template); ($template is defined in system.php).

All this works fine, however I can't find a way to echo $Skin->output from within system.php

I can output it by putting echo $template; inside the $Skin->output function but not from outside that...

Is there a way I can do this?

Hope you can follow what I said...

Thanks
