Help, No Rapid fire on M95.

Ok, so I have a M95 mouse and I have it set to where button number 9 should be rapid fire left click, but when I go to use it, no rapid fire. =/



Here is a screenshot so you can see for yourself, it's probably something simple I'm overlooking. Thanks in advance.

BTW I'm on Firmware 2.24, and Software version 1.00.00.14
