well that did the trick o.k Jazz. at least i have the motors turning which was a great milestone to reach. i have to play with it to day to get comfortable with the different noises and speeds . i thought i had a problem with having only 3 inputs available because i couldn't use input 10 or 11 .......... turned out that they only become available for use when the dedicated inputs on the bob are wired in!!! every day is a day for school!! cheers for that last night , by the way.
