custom page in vb3

[danrak]

Ok. I managed to find the code on here on how to add a custom page for vb2. But sadly, I can't get it to work with vb3. The code I was using is in the php file I created was:

<? 
require('global.php'); 

eval("dooutput(\"".gettemplate("pagename")."\");"); 
?> 

And added a template with pagename

But I get the following error message:
Fatal error: Call to undefined function: gettemplate() in /home/tsf/public_html/pagename.php on line 4

Is there anyway to fix this? How can I get a new blank custom page?
