Has anyone had trouble with PayPal viewcart and/or add to cart button functionality in Chapter 7? I can't get the view cart button to do anything when inserted in the HTML where demonstrated. Even weirder... When placed in a user control (such as Header.ascx) it will work, but ONLY if another View Cart button (or at least the form and hidden fields) are present on the Default.aspx webform. Also, if the button is placed in the table cell called pageContentsCell, the View Cart button will work but now the Add to Cart button won't!!
What's going on here?! When viewing the resulting source HTML from the browser it looks like it should work. Any help appreciated!!

Thank you
