Thanks guys, slow process to get the job running again, floor by floor and enter the count. We had no choice in swapping, the original was a little burnt.
Only issue now is that the car stops at all floors but does not open doors on the top two landings, after modifying the numbers of floors.
Quicker the client modernizes the better off we will be.
So if anyone has a quick fix for the above minor issue, would be appreciated.
