Another question about Beveling on Maya....

I followed the video as usual and still have problems.

Below are two screenshots first one shows that I have selected the entire object with Edge Tool...

The Second shows that nothing has taken effect after pressing the Bevel button from the Edit Mesh Menu.

Anybody know the reasons?...In the meantime I will look for the answers myself and try to figure out the problem.

Before Bevel
After Bevel and still nothing
