Error: Input string not in the correct format

[K0AMY]

Hello All.... Trying to import DB25 codeplug to GD88.
After reading from the GD88, I import the DB25 contacts export file .... that seems to go well. But, when I import the channels, I get the error,
"Input string not in correct format."
I have not uploaded anything to the GD88 radio at this point. Just trying to get the DB25 codeplug in the CPEditor (after reading from the GD88)
Any suggestions appreciated.

can you send me a link to the DB25 contact list? I am trying to program my radio.
