Help with Moving Lights and Fat Frog

[Scott]

Got a show coming up and its the first time I have used movers with the Fat Frog. I have two Giottos and I have managed to get them uploaded as Fixtures, but it will only let me work one at a time as I have to change the DMX address each time so I can only get the board talking to one light at a time, means I can't work them both. Also to work the lights each channel fader seems to work a function which is handy but the fixtures and palletts do not seem to be talking to the lights, help
