Passing in variables into a command via command group

[VaneRaklan]

Hello people of the world! Its me again, with another question pertaining to programming. So I am having trouble figuring out how to pass an argument into a command in a Command Group. I don't know if it a formatting thing within the command itself or if I am doing something else wrong. What I mean by passing the argument is say I have addSequential(new AutoDrive()); and I want to pass in a speed for the different times that I want to call it. So in turn i would say addSequential(new AutoDrive(.5)); or AutoDrive(1) or something like that. Anyone know how to do this?
