    set size [ns_set size $form]
     while {$i<$size} {
         if { [ns_set key $form $i] == $checkbox_name} {
             set value [ns_set value $form $i]
            check_for_form_variable_naughtiness $checkbox_name $value
             # LIST_TO_RETURN will be created if it doesn't exist
            lappend list_to_return $value
        }
        incr i
    }
     #if no list, you can specify a default return
     #default default is 0
     if { [info exists list_to_return] } { return $list_to_return } else {return $default_return}
