My if statement is being ignored

For some reason my if statement is being ignored and it will pass it going right to the else statement instead. Here is my code,

using UnityEngine;

public class Slide : MonoBehaviour {
	public float speed = 0.1f;
	private float posY = 5.75f;
	private string movement = "neutral";
	public void SlideDown() {
		movement = "down";
		//transform.position = new Vector3(-3.087039f, 5.75f, 5.192412f);
	}
	public void SlideUp() {
		movement = "up";
		//transform.position = new Vector3(-3.087039f, 9.5f, 5.192412f);
	}
	void Update() {
		if(movement == "down") 
			if (posY > 5.75) {
				posY -= speed;
				transform.position = new Vector3(-3.087039f, posY, 5.192412f);
			}else{
				movement = "neutral";
				transform.position = new Vector3(-3.087039f, 5.75f, 5.192412f);
				Debug.Log("down");
			}
		
		if (movement == "up") 
			if (posY < 9.5) {
				posY += speed;
				transform.position = new Vector3(-3.087039f, posY, 5.192412f);
			}else{
				movement = "neutral";
				transform.position = new Vector3(-3.087039f, 9.5f, 5.192412f);
				Debug.Log("up");
			}
		
	}
}

I don’t know what is wrong, please help.

Good day.

At

 void Update() {
         if(movement == "down") 
             if (posY > 5.75) {

you forget to open the { } for the movement == down if

Bye.
