[Plugin: MaxButtons: CSS3 Button Generator for WordPress] modifying button url in shortcode does not

I created a button and have been trying to modify the link in the shortcode to reuse the button style but it doesn’t work.

As an example when I place this shortcode:

[maxbutton id="3" url=”http://google.com”]

The button shows up fine, but the link doesn’t go directly to google. It instead goes to something like this:

http://www.mysite.com/2012/01/14/blue/”http:/google.com”

I can’t figure out what the problem is. Any help for this newbie would be great.

Thanks!
