In my define_main_page I have several form blocks that look like this where in 1.38a the customer would click the image and the product would be added to cart, instead of going over to the product info page first.

<form enctype="multipart/form-data" method="post" action="http://www.mystore.com/store/index.php?main_page=product_info&cPath=2&products_id=23&action=add_product" name="cart_quantity23">
<input type="hidden" value="1" name="cart_quantity"/>
<input type="hidden" value="23" name="products_id"/>
<input type="image" class="image" title=" Add to Cart " alt="Add to Cart" src="http://www.mystore.com/store/images/series1P.jpg"/>
</form>

I've upgraded to 1.50 and it has broken this functionality and also causes a 404 when they click the product image.

I don't know enough about 1.50 yet to know how to fix this. Can anyone help?

Thanks from Jennifer
