title: Excel VBA Listbox use of SelectedIndexChanged event
body: <p>I am trying to utilize the Excel VBA Listbox SelectedIndexChanged event to update a textbox on the same userform with the sum of the values in one column of my listbox as the user selects each row in that listbox.</p>
  
  <p>I can not figure out how to get the code for that event handler to execute.  Any suggestions?  I am using Excel VBA with the latest version of excel from office 365 on a windows 10 machine. In fact i don't even see that event listed in the pulldown when i have the code window up for that userform?</p>
  
  <p>Thanks
  Mike</p>
