title: Excel VBA Userform - Execute Sub when something changes
body: <p>I have a userform containing lots of text boxes. When ever the values of these text boxes changes, I need to recalculate my end result values based on the textbox values by calling a subroutine AutoCalc().</p>
  
  <p>I have around 25 boxes and I don't want to add a Change() event individually to each textbox calling the said subroutine. What's the quickest and efficient way to call the AutoCalc() whenever some value changes?</p>
