Thanks Greg,
Using your code I have sorted it, I’ve created 2 new template files in the child theme (category-top.php & category-bottom.php) and added your code in there and then included those new files in list.php – keeps things neater than way
Sorry another question – If I wanted to inject an ad inbetween the listings on the category page (after the 3rd listing for example) is that possible – jQuery maybe?
Thanks again
