Field validation on maximum value

[eluser]mdcode[/eluser]
Thanks for your reply, but this hasn't happened before... Even if I place callback_ in front of the condition, validation seemingly fails to run on this field at all. I really don't understand what's going on with it since I have tested the clause with PHP.

The posted field value and variable is set.
$this->db->count_all() is returning a variable.
Actions based on these values return as expected, except the validation... :question:
