controlclick not working

[roofninja 0]

I am having problems getting this control click to click. Below is the command that I am using. The strange thing is that this "Button" number keeps changing. One time it is Button15 the next it is Button6 and another time it is Button8. Below that I have saved the summery page for you to see.

What am I missing here to make it work?
