array in controller not recognized in rest of class' functions?

[eluser]Michael Wales[/eluser]
$rules is a class variable and the following line is referring to a local variable (a variable for that function only):

Code:

$input = userules_forinput($rules);     // **** LINE WITH UNDEFINED ERROR for $rules

Change it to:

Code:

$input = userules_forinput($this->rules);
