Pro-97 Help

[bhand]

I have a radio shack pro-97 scanner. I have recently began to program my scanner for the awin channels. My problem is that when i enter a talk group id in, and then the next, it shows duplicate message. IE; 2601, and then 2602. When i enter the second, it shows duplicate message. I dont know what to do, these are the id's thats on this website so i know there right. Is there a button i need to hit or will my radio just not work? I need help. Any suggestions would be great.
