I would just like to say thanks everyone for theyre help.
The problems I was having with Rons circuit were down to the fact that I am a goose. i have been an electrician now for 25yrs and when I look at a schematic always assume (the mother of all) when there are two components in a drawing, if they are part of the same assembly they are surrounded by dotted lines. So instead of using one CD4013 I used two and connected them up as U2A and U2B. Hence the second IC was missing supply voltage and much else besides.
Once this was rectified circuit worked like a dream so thanks again.
There is no such thing as a stupid question
