title: Custom function will not update automatically (settings are set to auto calculations!)
body: <p>I have a custom function that detects if a cell is bold</p>
  
  <pre><code>Function isBold(cellBold)
  If cellBold.Font.Bold = True Then
      isBold = 1
  ElseIf cellBold.Font.Bold = False Then
      isBold = 0
  Else
      isBold = 0
  End If
  
  End Function
  </code></pre>
  
  <p>Puts 1 in a cell if the reference cell is bold and 0 if it is not bold
  This works well and all the first time around but if I make the reference cell bold the number stays at 0. Automatic calculations are on, the only way for the function to calculate again is to retype the function</p>
