I just edited my inventory script to use the beginScrollView function. However my button to open the sub menu no longer works in it. Any ideas why? Go under assumption that all variables are defined. code:

function OnGUI() {

    numberOfItems = 0;

    buttonPosX = 10;

    buttonPosY = 25;

    if(openInventory == true)
    {

       if(openSubMenu == true)
       {
         SubMenu();
       }

       //begin scroll view
       scrollVector = GUI.BeginScrollView(Rect(0, 0, Screen.width/2, Screen.height/2),scrollVector, Rect(0, 0, 450, 450));

       //put stuff in scroll view
       GUI.TextArea(Rect(0,0,450,450), "INVENTORY");

       for(items in menuItems)
       {
         if(GUI.Button(Rect(buttonPosX, buttonPosY, 100, 50), items))
         {
          openSubMenu = true;
          currentItem = items;
         }

         buttonPosX = buttonPosX + 125;
         numberOfItems += 1;

         if(numberOfItems %4 == 0)
         {
          buttonPosX = 10;
          buttonPosY = buttonPosY + 115;
         }
       }

       GUI.EndScrollView();

       //GUI.Box(Rect(0, 0, Screen.width/2, Screen.height/2),"INVENTORY");
    }

    if(activateIW == true)
    {
       GUI.Box(Rect(Screen.width - 225, 10, 215,25), "object is already in your inventory");
    }

}
