It is quite easy to implement PayPal Mini Cart on to your web site but there is a simple error that can stop the cart from displaying on your web page.
When you create you web page, make sure that the web page has proper validation at the top of the page such as
<!DOCTYPE html PUBLIC “-//W3C//DTD XHTML 1.0 Transitional//EN” “http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd”>
<html xmlns=”http://www.w3.org/1999/xhtml”>
Secondly, the Javascript code should be poistioned at the bottom of the web page just above the </body> tag.
