Successfully reworked and now 2 Encoders working. Not going with the 3 as originally had planned at this point. Also added buttons of encoders but not necessary - may or may not use. If I use then I need to delve into a mapper which I was not going to do.
Now to get box complete. Still waiting on some gear to finish that.
Thanks for help all.
Attached copy of software setup. It took a while to find the button numbers for the encoders. Still not sure what has happened to "Button #1" It seems to have gone missing in action? Cheers
