    Hello HallsofIvy and many thanks for your reply.
    The best way I can describe what I mean be the Trend is as if you plot the data sequence as a graph in Excel and then add a trend line you can see if the number of one's to zero's is rising or falling. Any I had a soak in the bath on the problem and well I think it is simple arithmatic, unless I have mist something.
