Dynamically alter $stylevar['codeblockwidth']

[Antivirus]

I have been trying to dynamically alter the width of $stylevar['codeblockwidth'] based upon a condition in php, however it's not behaving as expected. It's just stretching to the max width to fit all the contents within the code tags.

I am inserting the following code into hook group_complete

PHP Code:

$stylevar['codeblockwidth']    = $vbulletin->options['scst_rightgblockwidth']; 


Anyone know why it's not working?
