error CS1501: No overload for method 'SetBool' takes 1 arguments

I’m trying to make a transition from idle to slide by pressing left shift but i got this error, here is the code. Please help.

}

private void HandleSlide()
{
	if (slide) 
	{
		myAnimator.SetBool ("slide");
	}
}

SetBool takes two arguments because it needs to know whether to set it false or true.
So

myAnimator.SetBool("slide", true);

you could also:

myAnimator.SetBool("slide", false);
