I,,,don't,,,understand,,,what,,,your,,,question,,,is???
Please be a little more specific. I can guess you are trying to manipulate cursors on a graph but if you found a VI, you should at least mention the name of it and where you got it. If you can't explain how your program works, attach it or a picture of the diagram.
And,,, please,,,clean,,,your,,,keyboard. It seems your comma key is sticking.
