Hi, does anyone know how to do this?

I have followed the instructions below:

"In /includes/templates/your_template/templates/tpl_product_info_display.php, move the block of code beginning with <!--bof Add to Cart Box --> to wherever in the sequence you want it to display. In some cases it will be necessary to tinker with <br class="clearBoth"> tags to get it working just right."

But nothing happens. Is there something i need to do in the admin?
