Change Price Display Order

I've altered product listing_img_title to display the price on the product listing page. No problem with that, except that the products that have two prices (eg Prime Rib Sliders: 3.25 for one/14.95 for six) are showing the wrong way round, with the price for 6 first. I want it to show price for one followed by price for six.

I've tried altering product listing_price - namely this section here:

echo '</span> ';
if(isset($price->price_min_quantity) && empty($this->cart_product_price) && $this->params->get('per_unit',1)){
if($price->price_min_quantity>1){
echo JText::sprintf('PER_UNIT_AT_LEAST_X_BOUGHT',$price->price_min_quantity);
}else{
echo JText::_('PER_UNIT');
}
}

But my knowledge of PHP is not good enough to know what I should be doing here. I'm sure it must be incredibly simple - could you point me in the right direction?

Thanks, Jen

Ok, thanks. I am attempting to show the total price for 1 and the total price for 6; I don't want the price-per-unit for 6. Currently I've set the prices as variants to get round this ordering issue, I'll try the method you suggested.

A related question: when using this method, is there any way to have the text "each" only after products for which there is more than one quantity option available? To clarify - for example, I want my menu item "Prime Rib Sliders" to display "$3.25 each (or) $14.95 for six"; I want my item "Potato Skins" (which has only one price) to just display "4.95", without the "each".

Thanks again for your support

OK, thanks.
