Variables not working

I have a variable (allowdraw) set to false originally. I have this code:


_root.water_btn.onRelease = function() {
    if (allowdraw == false) {
        allowdraw = true;
    } else {
        allowdraw = false
    }
};

It sets it to true when the button is released the first time, but won’t set it to false when I press it the second time. Can anyone help?
