Autonomous timeout

[Bennett]

We are trying to program autonomous code for our robot and in our commands we have

    public turnLeft() {
        m_timeout = timeout;
        requires(chassis);

but the m_timeout = timeout; says that m_timeout has private access in edu.wpi.first.wpilibj.command.Command
cannot find symbol
symbol: variable timeout
location:class edu.wpi.first.wpilibj.templates.commands.turnLeft

any ideas as to why?
thanks.
