I want to take the "Quantity in Cart (1)" information located on the tpl_product_info_display.php page and put it in my header.

I've got it working...almost. I can get the "Add to Cart" button, but I can't get the "quantity" info to show up.

At one point, out of desperation, I copied and pasted the entire product_info_display code into my header thinking that I could better determine my shortcomings but that didn't help. I can still see it in the body, but I can't get it show up in the header.

How would I do this?
