I'm trying to write a vba macro for autocad that opens Excel and then prompts the user to select a cell in Excel. One of the problems I'm having is getting the msgbox call to work. How do I get make a call to Excel to pop up a msgbox that prompts the user to do something? If I type msgbox "blah" in my Acad macro without any reference to Excel the screen returns to Acad when I want it to stay in Excel. Thanks, Rob
