Fed up! Why isn't this working? $vbulletin->options['hiddensigson']

[BirdOPrey5]

OK I made a new option, var name: hiddensigon
yesno type
default: 0
I double checked all the settings from a working mod and they are indentical besides the var name...

Then in my plugin I use an if statement:

PHP Code:

if ($vbulletin->options['hiddensigson'])
{
//code
} 


But even when I turn the option to "Yes" it never executes the code... when I try to output the variable just to see what it is, I get nothing at all... $vbulletin->options['hiddensigson'] resolves to nothing...

can't figure out what is wrong.
