I had the same issue gdisalvo, but I found that I had an extra “; after
<input type=’text’ id=’smcf-phone’ class=’smcf-input’ name=’phone’ value=” tabindex=’1003′ />
Just make sure “; comes after the last field in your list.
I deleted the extra one and it worked great.
I found this as a solution
[product_categories number=”12″ parent=”0″]
Set the parent paramater to 0 to only display top level categories.
I needed only the parent categories to show on my homepage – or wherever you use that shortcode.
