title: VBA: Initialize Combo Box in worksheet
body: <p>I have an error during initialization and I do not get why this is not working:</p>
  
  <pre><code>Private Sub Workbook_Open()
  Dim ws As Worksheet
  
  Set ws = Worksheets(1)
  
  
  ws.ComboC15.AddItem "Technology"
  end sub
  </code></pre>
  
  <p>It is very weird, the code should be correct. I have checked the combo name and it is "ComboC15". </p>
  
  <p>In fact, this is the sub:</p>
  
  <pre><code> Private Sub ComboC15_Change()
  </code></pre>
  
  <p>Ps: I also checked the sheet and it is the first sheet where I have the Combo</p>
