Hello, I'm not sure what you are asking, sorry. Can you do...
Header 100%
Div Wrapper
Div Left 40%
Div Middle 30%
Div Right 30%
/Div Wrapper
Div Footer 100%
If you look in the templates you will see things like {NAME->info} so you could set $PHORUM['DATA']['NAME']['info
2'] = $your_output; in your PHP file, and then use {NAME->info
2} in the same template you found {NAME->info} assuming your PHP code is in the right spot for use in the template. Just be sure info
2 isn't already used to avoid overwriting some variable.
Not sure if that is what you are asking.
