Douglas MD81

Hello,
I downloaded the MD81, and I want to thank you all for that and will continue to support the website. I have one problem with the plane and that is I cannot change com frequency on the panel. I can change the nav freqs but not the com freqs. Can you help me correct this??
Thanks
