Ultrasonic sensor option missing in Wait block in Labview
Once you download the block from the Lego site, you can import it into the LabVIEW by using the Tools tab and then Block Import, but first you need to be in an open program.  LabVIEW will prompt you to browse your folders to find the downloaded file, and then select Import at the bottom of the window.  Finally, you will need to close LabVIEW and reopen it to begin using the block in all of your programs.
