Not redirecting to cart on one page only

Hi all
My development is progressing but my index.asp page won't redirect to cart.asp anymore. It adds the selection to cart, but doesn't redirect. I must have changed something somewhere, but everything looks exactly the same as the successful pages to me.

Also, I've tried to add 'items in cart' next to my cart icon but it won't work - I've tried using variations of the TotalColumn solutions I've found in here, but my cart.asp doesn't have a quantity column - could that be causing the problem?

Any help would be appreciated, thx

add the following code to the index page just before the doctype tag:
<%
' WA eCart Redirect
if (bookshop_redirStr <> "") then
Response.Redirect(bookshop_redirStr)
end if
%>
