trouble accessing datastore

[VodkaFish]

An update to my situation:

PHP Code:

var_dump($vbulletin->mystuff); 


Nothing happens.

PHP Code:

$lots = $vbulletin->datastore->do_db_fetch("'mystuff'");
echo $lots; 


Nothing happens.

PHP Code:

$lots = $vbulletin->datastore->do_db_fetch("'mystuff'");
var_dump($vbulletin->mystuff); 


That will give me the data I want in a test file. The custom mod I use that code in still isn't working, but that could be from another part of it.
