Setting up animation controller, need help with script for touch movement..

Edit: I found my solution. Given how I had things set up, it ended up being very easy to designate a bool to the animation controller as opposed to a float. I posted a bit more info in my comment below.

Let me preface this by saying I'm a total beginner. I am trying to rig up a 2d character so that the animation changes based on its horizontal movement speed by having left and right movement animations. For this I watched the Live Unity training video here: https://www.youtube.com/watch?v=Xnyb2f6Qqzg

I then wrote (copied) the code. My problem is I want my animations to changed based on clicking GUI textures which produce movement speed as opposed to the arrow keys which are used through the float move = Input.GetAxis("Horizontal") line. If anyone could explain how I could take the Unity live code and apply it to the touch based movement code I have, it would be greatly appreciated. I have a feeling I need to create a different anim.SetFloat, but I don't know exactly what to do. I will first put the Unity live script, and then follow it with the code I'm using for touch controls. Thanks for the help guys.

         float move = Input.GetAxis ("Horizontal");
         rigidbody2D.velocity = new Vector2 (move * maxSpeed, rigidbody2D.velocity.y);
 
         anim.SetFloat ("Speed", Mathf.Abs(move));
 
         if (move > 0 && facingRight)
             Flip ();
         else if (move < 0 && !facingRight)
             Flip ();
     }

         theScale.x *= -1;
