<br> This is the problem when viewing the "diagram" versus actually using the VI. As I said in my first response, the Mechanical Action of the button is important -- it should be 'Latch When Released.'
Right-click on the button, select Mechanical Action, and then select 'Latch When Released.' This will give you the desired behavior with my diagram. Try it. As for the in-depth fundamentals of G programming, in addition to the Online Help, and manuals, you may want to consider taking an Advanced LabVIEW course from NI. Here's the link for the training dept.: http://www.ni.com/training/ Can you attach your version of the VI so we can know why it isn't doing what you want it to do. Thanks, <i>Khalid</i> <br>
