Object reference not set to an instance of an object (797427)

Hello, hope you’re well. I’m trying to make it so once a timer reaches zero, a Float (which is defined in another script) should have 10 added to it. This isn’t working, and the error I’m getting is “NullReferenceException: Object reference not set to an instance of an object”. Here is the code where the float is defined:

public class SeedNeed : MonoBehaviour
{

    public float currentNeed = 15f;
 

   
   
}

And here’s the code which is trying to make it so when the timer (timeLeft) reaches zero, 10 is added to currentNeed in the first script:

public class harvesting : MonoBehaviour
{

    public float timeLeft = 10f;
    public SeedNeed seeedNeed;
   
     public void Update()
    {
        timeLeft -= Time.deltaTime;

        if (timeLeft <= 0)
        {
            Debug.Log("IM READY TO HARVEST");
           
            seeedNeed.currentNeed += 10;      
        }     
    }
}

Please help, this seemed like a simple enough problem, yet it is very difficult to fix. Thanks!

means this script is not attached to an object or its execution order is low then second script
