I will try and attempt an answer to your question. If i understand your scenario correctly it seems you have 3 switches in a the following setup (Hope the ascii comes out correctly)
If that is so than you can use channel-group 1 to form the etherchannel between SW1 and SW2. however on SW1 you have to use a different channel-group. If you look at show etherchannel summary with the way you have it configured now you would see that all the ports F0/19 - F0/22 are configured under the same etherchannel which basically means they are going to the same device and this is not correct because you have 2 ports going to SW2 and 2 ports going to SW3.
