Please verify that you have pasted the code in its entirety correctly.  Also check that the first section of the code is placed between the <head> tags in your HTML code and that the second part of the code is placed where you want the widget to appear in your web page.

If this still does not solve your problem, verify that your browser does not block JS code and that your hosting provider allows you to host JS code.
