I have a scrollbar on a worksheet that updates information with each click, including a graph. It is ideal to be able to automate the scrollbar progression with a specific time delay, say 500ms. I figured I would need a toggle button whose caption is "start" until the button is clicked initially to start a timer, and then "stop" until the button is clicked again to stop the progression. However, I'm not quite sure how to go about programming this button. Any thoughts?? Thanks
