title: How to come back to Save message box when clicking "No" to replace file
body: <p>In Excel-VBA, I am saving a file using the following code:</p>
  
  <pre><code>fullFileName = Application.GetSaveAsFilename(...)
  ActiveWorkbook.SaveAs fullFileName
  </code></pre>
  
  <p>This works fine until the name chosen already exists. The message box then prompts: "Should the file be replaced?". I want to answer <code>No</code>, and return to the previous message box and chose another name.</p>
  
  <p>Instead, clicking <code>No</code> interrupts the macro and produces an error.</p>
  
  <p>How could I solve this?</p>
  
  <p>(The web is full of examples showing how to bypass this message box using <code>Application.DisplayAlerts=False</code> and save anyway. This is not what I want!)</p>
