flashbuilder 4.6 / flex - how to use if then to check toggleswitch value

I have an app Im building with that I want to have a toggleswitch control whether or not a function STOPS running or Whether it should RESTART.

how to I set this up? I've tried

if (toggleswitch1.thumbPosition = 0) {
    trace("The function should STOP");              
} else {
trace("The function should RESTART");
}

If you're using a ToggleSwitch ; you can just use the selected property to determine the state of the button.

if (toggleswitch1.selected == false) {
    trace("The function should STOP");              
} else {
trace("The function should RESTART");
}

Also, as a critique of your code; this line toggleswitch1.thumbPosition = 0 is an assignment and will always return true. If you want to check for equality be sure to use the double equal sign '==' instead of the single equal sign '='.
