C# int not defined,Int not valid type in C#

I have t$$anonymous$$s code:

 using System.Collections;
 using System.Collections.Generic;
 using UnityEngine;
 
 
 public class Script : MonoBehaviour
 {
     Int ForceAmmount = 500;
     Int BaseAmmount = 500;
     Rigidbody rb;
     // Start is called before the first frame update
     void Start()
     {
         rb = GetComponent<Rigidbody>();
     }
 
 
 
     // Update is called once per frame
     void Update()
     {
         if (Input.GetKeyDown(KeyCode.Space))
         {
             rb.AddForce(Vector3.up = ForceAmmount);
             ForceAmmount = ForceAmmount - 10;
 
             if (ForceAmmount == 0)
             {
                 BaseAmmount = BaseAmmount + 10;
                 ForceAmmount = BaseAmmount;
             }
             print(ForceAmmount);
         }
     }
 
     private void OnMouseDown()
     {
         rb.AddForce(Vector3.up = ForceAmmount);
         ForceAmmount = ForceAmmount - 10;
 
         if (ForceAmmount == 0)
         {
             BaseAmmount = BaseAmmount + 10;
             ForceAmmount = BaseAmmount;
         }
         print(ForceAmmount);
     }
 
     private void OnCollisionEnter(Collision collision)
     {
         if (collision.gameObject.tag == "Death")
         {
             Destroy(gameObject);
         }
         
     }
 
 
 
 }
 `
 and when I Save it and look at the Unity window I get two errors for the two integers I define:Assets\Script.cs(9,5): error CS0246: The type or namespace name 'Int' could not be found (are you missing a using directive or an assembly reference?)
 
  I don't know why t$$anonymous$$s is happening. also, I know that the code is messed up IDK what that is either
 
 ,I have t$$anonymous$$s code:`using System.Collections;
 using System.Collections.Generic;
 using UnityEngine;
 
 
 public class Script : MonoBehaviour
 {
     Int ForceAmmount = 500;
     Int BaseAmmount = 500;
     Rigidbody rb;
     // Start is called before the first frame update
     void Start()
     {
         rb = GetComponent<Rigidbody>();
     }
 
 
 
     // Update is called once per frame
     void Update()
     {
         if (Input.GetKeyDown(KeyCode.Space))
         {
             rb.AddForce(Vector3.up = ForceAmmount);
             ForceAmmount = ForceAmmount - 10;
 
             if (ForceAmmount == 0)
             {
                 BaseAmmount = BaseAmmount + 10;
                 ForceAmmount = BaseAmmount;
             }
             print(ForceAmmount);
         }
     }
 
     private void OnMouseDown()
     {
         rb.AddForce(Vector3.up = ForceAmmount);
         ForceAmmount = ForceAmmount - 10;
 
         if (ForceAmmount == 0)
         {
             BaseAmmount = BaseAmmount + 10;
             ForceAmmount = BaseAmmount;
         }
         print(ForceAmmount);
     }
 
     private void OnCollisionEnter(Collision collision)
     {
         if (collision.gameObject.tag == "Death")
         {
             Destroy(gameObject);
         }
         
     }
 
 
 
 }

In the beginning, I define two integers but when I save the program it says: Assets\Script.cs(9,5): error CS0246: The type or namespace name 'Int' could not be found (are you missing a using directive or an assembly reference?) A w$$anonymous$$le ago my code for defining the integers worked and didn't bring an error. I don't know why t$$anonymous$$s is happening.
