[solved]Custom Validation?

Sorry

Well for instance I put in a time of this in my form "42:43:60"

It should return a message saying "The %s time fields Hour segment is not correct."

There is just a blank white page.

To test I have this just after my validation:

Code:

$this->form_validation->set_rules('time'.$i, 'Time'.($i+1), 'required|xss_clean|callback_valid_time'); // time0, time1, time2 etc

echo validation_errors();
return;

Using the example I used "$str" which I am guessing is a variable passed to my custom function from the form_validation class?
