Problems coding for form_radio()

[eluser]mddd[/eluser]
You are mixing up the two uses of form_radio:
1. form_radio($name, $value, $checked_or_not);
2. form_radio($array_of_attributes);

If you provide an array for the attributes of the radio button (method 2), then you should not provide the name separately.
So your form code should be:

Code:

<?php echo form_radio($input_common['cash']); ?>
