Form_validation message[SOLVED]

[eluser]Ivar89[/eluser]
Hi,
I have a contact form with some required fields And standard induvidual message is:
The "field name" field is required.

Now I want to change it to something else...and its not working
I need to change every field induvidually and if I use:

Code:

$this->form_validation->set_message('required',  'Niet alle velden zijn correct ingevoerd.');

It changes ALL fields with the rule required to that message
but is there a way I can set a message not connected to a rule but to like an ID??
I can't find this in the user guide.

Thanks in advance.
