Well that works. Just bummed that I can't use my custom button. There's no way I can use the custom button to accomplish the same thing? I've already design the entire site with the products and just wanted to pop a custom, buy it now, button.
If I edit the add to cart button inside hikashop, and then use the:
<input type="submit" onclick="var field=document.getElementById('hikashop_product_quantity_field_1');return hikashopModifyQuantity('2',field,1,0);" value="Add to cart" name="add" class="button hikashop_cart_input_button">
Would that work?
Edit: I know I accomplished this before and the trick was as simple as changing some code into the custom button, I just can't remember how.
