Central score counter for 3 score generating buttons

Hey folks,

I’m working on a mobile project that requires score to be collected from 3 score generating buttons. All three buttons have different point value assigned to them. I have:
Snow button for 25 points.
DJ button for 50 points.
SnS button for 100 points.

I need to collect the score on a central collector but I’m having an issue. When I press the same button multiple times the counter works fine but as soon as I hit one of the other buttons, the counter resets back to 0 before adding the points from that button on.

I’ve seen this problem solved when colliders and OnTriggerEnter are involved but I am quite new to this so I’m struggling to apply those tutorials to my buttons.

Heres my code that I adapted from a tutorial:

using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using UnityEngine.UI;

public class ButtonClickScriptSnow : MonoBehaviour
{
public Button button;
public Text text;

public int currentPoints =0;
public int currentScore;

public void ClickButton()
{
    if (button != null)
    {
        currentScore = currentPoints + 25;
        if (text != null)
        {
            text.text = "" + currentScore.ToString();
        }
    }
}

}

I change the point value and the name of the code for each button. Any help is appreciated, thanks.

Fixed. Combined all three button codes into one and made more ClickButton functions.

using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using UnityEngine.UI;

public class ButtonClickScript : MonoBehaviour
{
public Button DJbutton;
public Button SnSbutton;
public Button Snowbutton;
public Text text;

public int currentPoints = 0;
public int snowPoints;
public int snsPoints;
public int djPoints;

public void ClickButton1()
{
    if (DJbutton != null)
    {
        djPoints = djPoints + 50;
        currentPoints = djPoints + snowPoints + snsPoints;
        if (text != null)
        {
            text.text = "" + currentPoints.ToString();
        }
    }
}
public void ClickButton2()
{
    if (SnSbutton != null)
    {
        snsPoints = snsPoints + 100;
        currentPoints = djPoints + snowPoints + snsPoints;
        if (text != null)
        {
            text.text = "" + currentPoints.ToString();
        }
    }
}
public void ClickButton3()
{
    if (Snowbutton != null)
    {
        snowPoints = snowPoints + 25;
        currentPoints = djPoints + snowPoints + snsPoints;
        if (text != null)
        {
            text.text = "" + currentPoints.ToString();
        }
    }
}

}
