sidebar php problems ... ???

[alanshort]

Hey All

I'm trying to create a custom sidebar block in my forum.

the text and html options work fine, however when trying to use the php option, it displays the text at the very top of the page and not in the sidebar ... ?

i.e

if i create a new php block containing :

echo "hello world!";

then this is displayed at the very top of the page and not in the side bar....

What am i doing wrong ???

Cheers
A
