maintaining clickies with zero checked produces warning/error

The warning/error is not produced when atleast one clickie is clicked. This is probably because foreach doesn't know how to handle zero things. I propose a solution:

try {
    //foreach stuff here
} catch (Exception $e) {
    echo "You need to click the checkboxes next to the clickies you wish to maintain.";
}

For those interested, the proper solution is:

//Checks to make sure $data is an array before iterating
if(is_array($data)) {
    foreach($data as $d) {
        //do somethign with $d
    }
}

Because, regardless of the language, exceptions are expensive. Of course, depending on the language, *cough*MaxScript*cough* returns, breaks, and continues can also be expensive... (for some absurd reason Autodesk implemented them using C++ exceptions internally)

Fixed.
