Can´t instantiate objects in list correctly

Questions & Answers
1

The method is called when my document gameobject is picked and added to, the list i have (documents)
When I have only 1 item in my list, the I can grab the documents info (title, etc), and make them show them the info in my UI when clicked, not necessary to post that method.

BUT, when I have 2 or more items in my list, I cannot access any item in the document list anymore, I believe its the int (documentIDToinstance), what this does is instantiating the correct “.document” info to the new UI element, so it shows like the actual document

 public void PickedDocumentUp()
    {


        GameObject newbuttonToInst = Instantiate(FilePrefab);

        newbuttonToInst.name = documents[documentIDToInstance].documentTitle;
        newbuttonToInst.transform.parent = gameObject.transform;                    //Sets where to instantiate the newButton
        newbuttonToInst.transform.localScale = new Vector3(1f, 1f, 1f);             //Sets the correct scale of the newButton
        newbuttonToInst.GetComponent<Button>().onClick.AddListener(() => { ReadClickedDocument(); }); //Set the function to read the document

        Component[] components;
        components = GetComponentsInChildren<Text>();

        components[0].GetComponent<Text>().text = documents[documentIDToInstance].documentTPreview;   //Take and set the taken document title
        components[1].GetComponent<Text>().text = documents[documentIDToInstance].documentTitle;     //Take and set the taken document body
        components[2].GetComponent<Text>().text = documents[documentIDToInstance].documentBody; //Set the document preview
        
        
        //_documentTPreview.text = documents[documentIDToInstance].documentTPreview;

        documentIDToInstance = documents.Count;


    }

I hope I explained myself well. Hope anybody can guide me or show me some solutions. I believe the error is when instantiating the prefabs. Thanks!

You know that first index in array start at 0 (zero), so i not undestand why you assign here “documentIDToInstance = documents.Count;” Maybe you need “documentIDToInstance = documents.Count - 1;” Sorry if i wrong.
