My new radios only work after reload

Hello again Folks.I have scripted new XML radios to show on a popup window in an MFD type background. After some help they work just fine. However, I now find that they don't work on initial a/c load. I have to select another a/c then reload 'my' a/c to make the radio freqs. change.Is there a known reason for this type of thing or should I post my selector knob script?Regards...Kenny
