Magento : Default to the first item for all required options

Stick the code into 

app/design/frontend/default/theme/template/catalog/product/view/options.phtml

near the end of the file look for this line: 

var opConfig = new Product.Options(<?php echo $this->getJsonConfig() ?>);

and replace with this:

var opConfig = new Product.Options(<?php echo $this->getJsonConfig() ?>);Event.observe(window, 'load', function() {$$('.product-options select').each(function(element) {
element.selectedIndex = 1;opConfig.reloadPrice();});});







Refresh cache and load a product on the frontend which has custom options - after the page loads an option should automatically be selected.
