Instantiating object from inventory

I almost have a function inventory for my project, but when i try deploying my object through my inventory, it says "the prefab you want to instantiate is null" even though the object its looking for in my assets is indeed a prefab with the same name and is blue. heres the code:

 function OnGUI() {
 
 //var openSubMenu = false;
 
 inventoryStyle.normal.background = guiBackground;
 
     if(iWasPressed && timesPressed == 1)
     {
         Time.timeScale = 0;
         inventoryOpen = true;
         GUI.Box(Rect(guiX, guiY, guiWidth, guiHeight), "inventory", inventoryStyle);
         if(GUI.Button(Rect(15,30,75,75), slot1) && slot1Empty == false)
         {
             openSubMenu = true;
         }
         if(GUI.Button(Rect(160,30,75,75), slot2) && slot2Empty == false)
         {
             openSubMenu = true;
         }
         
         if(openSubMenu == true)
         {
             GUI.Box(Rect((Screen.width - 150)/2, (Screen.height - 100)/2, 150, 100), "drop object", subMenuStyle);
             if(GUI.Button(Rect((Screen.width - 125)/2, (Screen.height - 25)/2, 50,50), "Yes"))
             {
                 Debug.Log(deployObject.name + "is the instancing object");
                 var droppedObject = Instantiate(Resources.Load(deployObject.name), Vector3(transform.position.x, transform.position.y, transform.position.z + 5),
                 Quaternion.identity);
                 openSubMenu = false;
             }
             
             if(GUI.Button(Rect((Screen.width + 25)/2, (Screen.height - 25)/2, 50,50), "No"))
             {
                 openSubMenu = false;
             }
         }    
     }
     
     if(timesPressed < 1 | timesPressed > 1)
     {
         inventoryOpen = false;
         Time.timeScale = 1;
     }
 
 }
 
 function ObjectImageSwap() {
 
 if(selectedObject.name == "testObject1")
 {
     slot1Empty = false;
     slot1 = testImage;
     if(slot1 == testImage)
     {
         Debug.Log("slot1 should be test image");
         deployObject = gameObject.Find("testObject1");
     }
 }
 
 if(selectedObject.name == "testObject2")
 {
     slot2Empty = false;
     slot2 = testImage2;
     if(slot2 == testImage2)
     {
         Debug.Log("slot2 should be test image2");
         deployObject = gameObject.Find("testObject2");
     }
 }
 
 }
 
 if(!slot1)
 {
     slot1 = defaultImage;
     slot1Empty = true; 
 }
 
 if(slot1)
 {
     slot1Empty = false;
 }
 
 if(slot1 == defaultImage)
 {
     slot1Empty = true;
 }
 
 if(!slot2)
 {
     slot2 = defaultImage;
     slot2Empty = true;
 }
 
 if(slot2 == defaultImage)
 {
     slot2Empty = true;
 }
 
 if(slot2 == testImage2)
 {
     deployObject = gameObject.Find("testObject2");
 }
