If you want to do the plotting when the user selects the button labeled 'U', then you should be comparing the 'selectedButton.Text' field. The SelectedObject returns the whole UI object for the button that was chosen, so you can extract the field 'Text' to get the string that appears on the button. Hope this helps and have fun with App Designer!
