title: Attach Existing UserForm Button to Excel Workbook Sheet
body: <p>I have an Excel workbook that has a macro (the only macro in the workbook) attached to a button on a sheet.</p>
  
  <p>In VB mode, I created a UserForm under Forms with a CommandButton1_Click Sub and when run from within VB (Run > Run Sub/UserForm or F5) it runs fine.  I have it calling a Shell command that runs a BAT file that runs a Python script.</p>
  
  <p>How do I run CommandButton1_Click from a button on a sheet? If I try to add a button to a sheet, it offers me the macro I have already associated with the other button.</p>
