title: Runtime error '380' Could not set the Value property. Invalid property value
body: <p>I have a combobox inside of page of multipage object in a userform. </p>
  
  <p>Problem comes when code runs this statement:</p>
  
  <pre><code>'Trying to set the initial value
   userForm.comboBox.Value = "String"
  </code></pre>
  
  <p>Where "String" don't match with any of items of combo list.
  I checked MatchRequired property and is set to False but the error still coming.</p>
  
  <p>This works:</p>
  
  <pre><code>userForm.comboBox.Value = "Item_1"
  </code></pre>
  
  <p>Where Item_1 belongs to items list.</p>
  
  <p>Error message is: "Runtime error '380'
  Could not set the Value property. Invalid property value."</p>
  
  <p>What I'm missing? Thanks in advance.</p>
