Problem with a multi-jump script ( C# )

Questions & Answers
1

As the title says, i have a problem with a script that should allow me make a multi-jump with a JumpCount wich is going to run out after 4 jumps and recharge when i touch the ground. The script does not give any error, but i think there is something wrong directly in the script’s drawing up It simply doesen’t work when i apply it, my character jumps just one time.

using UnityEngine;
using System.Collections;

public class Volo : MonoBehaviour {
	float jumpCount;
	public Vector2 jumpForce = new Vector2(0, 300);
	bool grounded;
	void Update()
	{
		// If the character has more than 0 jumps left
		if (Input. GetKeyDown("space") && jumpCount > 0)
		{
			GetComponent<Rigidbody2D>().velocity = Vector2.zero;
			GetComponent<Rigidbody2D>().AddForce(jumpForce);
			jumpCount--; // Reduce the amount of jumps left by 1
		}
		// If the character is touching the ground
		if (grounded)
		{
			jumpCount = 4; // Reset amount of jumps left to 4
		}
	}
	
	void OnCollisionEnter(Collision col) // When the character collides with something
	{
		if(col.collider.tag == "ground") // If the object has the tag "ground"
		{
			grounded = true;
		}
	}
	void OnCollisionExit(Collision col) // When the character stops colliding with something
	{
		if(col.collider.tag == "ground") // If the object has the tag "ground"
		{
			grounded = false;
		}
	}
}

if (Input. GetKeyDown("space") && jumpCount > 0) there is a space after “Input.” looks like a syntax error, remove the space and try it.
