Thank-you Jim... but you failed to mention that without you and Peter mentoring me throughout I may well have fallen at the first hurdle. As it was, I had put the entire project on the back burner, considering it beyond my capabilities, and it was only when the Convid lock-down occurred that I brought it to the fore again. Thank-you once again. You and Peter continue to fly my flag and it is much appreciated.
