It looks like you're working on a script in C# for a Unity game. Here are a few suggestions and corrections for your code:

1. In the `Start` method, you're trying to get the `Shaft` component with `GetComponent()`, but you need to specify the type `Shaft` inside the parentheses.

2. In the `Upgrade` method, your for loop is missing the closing bracket and condition.

3. You may want to add a check in the `Upgrade` method to ensure that the player has enough money to perform the upgrade.

Here's an updated version of your script with these corrections:

```csharp

using System.Collections;

using System.Collections.Generic;

using UnityEngine;

public class BaseUpgrade : MonoBehaviour

{

private float moneyTest;

[SerializeField] protected float collectCapacityMultiplier = 2f;

[SerializeField] protected float polivDurationMultiplier = 0.9f;

[SerializeField] protected float moveSpeedMultiplier;

[SerializeField] protected float initialUpgradeCost = 200;

[SerializeField] protected float upgradeCostMultiplier = 2f;

public int CurrentLevel { get; set; }

public float UpgradeCost { get; set; }

protected Shaft shaft;

void Start()

{

shaft = GetComponent<Shaft>();

CurrentLevel = 1;

UpgradeCost = initialUpgradeCost;

}

public virtual void Upgrade(int upgradeAmount)

{

if (upgradeAmount > 0 && moneyTest >= UpgradeCost)

{

for (int i = 0; i < upgradeAmount; i++)

{

UpgradeSuccess();

UpdateUpgradeValues();

RunUpgrade();

}

}

}

protected virtual void UpgradeSuccess()

{

CurrentLevel++;

}

protected virtual void UpdateUpgradeValues()

{

UpgradeCost *= upgradeCostMultiplier;

}

protected virtual void RunUpgrade()

{

// Add your upgrade logic here

}

}

```

Make sure to fill in the upgrade logic inside the `RunUpgrade` method as per your game's requirements.
