I've added a button to my spreadsheet and I've added both a UserForm named frmInput and a modual but I can't find a way to get the button to launch my userform. After researching, I understand I need to add frmInput.show but I haven't found anywhere (in either the frmInput or the modual) to add that line, that launches the Userform.

I intended to include the version of Excel that I'm using but apparently the traditional "About" button is no longer traditional so I have no idea what version I'm using.
Any clues you have to offer would be appreciated. Thanks
