Input:
It turns out the belt was the wrong size.  The website was very confusing and I found it very difficult to understand , not user friendly, so I was not aware I had ordered the wrong size belt.  I have the Hoover Windtunnel vacuum and thought all belts would be pretty basic and the same.  Now I have to dig out the manual for the vacuum to get the parts # and locate somewhere locally to purchase the belt.
