Problem referencing an int inside of a dictionary.

So I have a dictionary set up to contain two variables, a string indicating the name of the object, and an int indicating how many of that object the player has. I'm trying to get this script to activate a button when the player has an item, and then display how many of that item the player has.

     public void ServerCardAddCount(string GPUname, GameObject Button)
     {
         if (Inventory.GPUCountDic[GPUname] <= 0)
         {
             Button.GetComponent<Button>().interactable = false;
         }
         else
         {
             Button.GetComponent<Button>().interactable = true;
             TenEightyAddButton.GetComponent<Text>().text = "Add 1080: " + Inventory.GPUCountDic["GTX 1080"] + "in inventory";
             TenSeventyAddButton.GetComponent<Text>().text = "Add 1070: " + Inventory.GPUCountDic["GTX 1070"] + "in inventory";
             TenSixtyAddButton.GetComponent<Text>().text = "Add 1060: " + Inventory.GPUCountDic["GTX 1060"] + "in inventory";
         }

The button activates and deacivates based on how if the player has that item just fine, but when the button is set to true, the console spits out

NullReferenceException: Object reference not set to an instance of an object

And then points me to the first line of code displaying the object count.

The dictionary is created in the Start() function of another script.

 {
     
     public static Dictionary<string, int> GPUCountDic = new Dictionary<string, int>();
 
     public void Start()
     {
         GPUCountDic.Add("GTX 1080", 0);
         GPUCountDic.Add("GTX 1070", 0);
         GPUCountDic.Add("GTX 1060", 0);
     }

Any help would be awesome.
