this cute hack for the modification of cart contents....
"You may or may not want this very basic hack I made to

cart quantities for modification. Likely many others
have hit upon it as well. It's in web_store_html_lib.pl."
if ($reason_to_display_cart =~ /change*quantity/i)
<TD ALIGN = "center">
<INPUT TYPE = "text" NAME = "$cart_row_number" VALUE="$quantity"
