My bool function isnt running in my code and i cant figure out why.

Here is code it can be copied and pasted into a project as it uses its own UI and etc

 using System.Collections;
 using System.Collections.Generic;
 using UnityEngine;
 using System.Text;
 using System.IO;
 using System;
 using System.Text.RegularExpressions;
 
 [ExecuteAlways]
 public class Scan : MonoBehaviour
 {
     public string SaveName;
     public CVSDATA CurrentInput;
     public List<CVSDATA> ScannerData = new List<CVSDATA>();
     string tempPrice;
     public bool Pressed;
 
     [System.Serializable]
     public class CVSDATA
     {
         public string rowDataPLU;
         public string rowDataName;
         public string rowDataPrice;
         public int rowDataCount;
     }
     
     void OnGUI()
     {
         CurrentInput.rowDataPLU = GUI.TextArea(new Rect(0, Screen.height - 90, Screen.width, 30), CurrentInput.rowDataPLU);
         CurrentInput.rowDataPLU = Regex.Replace(CurrentInput.rowDataPLU, @"[^0-9]", string.Empty);
         tempPrice = GUI.TextArea(new Rect(0, Screen.height - 60, Screen.width, 30), tempPrice);        
         if (GUI.Button(new Rect(0, Screen.height - 30, Screen.width, 30), "Scan"))
         {
             Pressed = true;
             Debug.Log("Button Pressed");
         }
     }
    
     // Update is called once per frame
     void Update()
     {
         if (tempPrice != null)
         {
             tempPrice = Regex.Replace(tempPrice, @"[^0-9 .]", string.Empty);
             CurrentInput.rowDataPrice = tempPrice;
         }
         if(Pressed)
         {
             for (int x = 0; x < ScannerData.Count; x++)
             {
                 if (ScannerData[x].rowDataPLU != CurrentInput.rowDataPLU)
                 {
                     ScannerData.Add(CurrentInput);
                     Pressed = false;
                 }
                 else
                 {
                     ScannerData[x].rowDataCount = ScannerData[x].rowDataCount + CurrentInput.rowDataCount;
                     Pressed = false;
                 }
             }
         }
         
     }
 }
