Adding Field to Checkout

[kuroi]

I found

function zen_draw_radio_field($name, $value = '', $checked = false, $parameters = '') {
    return zen_draw_selection_field($name, 'radio', $value, $checked, $parameters);
  } 

in includes/functions/html_output.php and I can get it to show a button on the page if i declair $name, $value, but i have no idea what $parameters should be.

Obviously I have more than one set of options and values so im at a loss on how to get my options and values output onto the page.

Parameters is a catch-all for anything else you need e.g. 'class="myRadioButton"'. You don't have to put anything in there if you don't need anything.

You would use this function once of each option/value combination, grouping the options by giving them the same name, with each value for that option having its own unique value.

You'll probably want to sprinkle lightly with LABEL tags too.
