                        ADD TO CART
                    
        </button>

The above is the html code for choosing a size and then clicking add to cart. I want to click size 8 in the drop down menu and then click add to cart. I see that the button id for the add to cart is "buyingtools-add-to-cart-button". How do I simulate a click on this button?

Can you provide a link to the website?

Did you try _IEFormSubmit? How about _IEGetObjById and _IEAction?
