Prefilling my select menu and Radio button

[eluser]harpster[/eluser]
Not sure if this helps but this is what I do and the radios stick...

Code:

<?php echo form_radio("gender", "Male", (set_value("gender") == "Male") ); ?> Male  
<?php echo form_radio("gender", "Female", (set_value("gender") == "Female") ); ?> Female <?php echo form_error('gender'); ?>

with this validation rule in the controller

Code:

$this->form_validation->set_rules('gender', 'Gender', 'required');
