Thanks to all that’s helped me.
The main part I think ive got in the bag… I just keep playing about with new samba installs now testing different things. 
I think the hardest thing to grasp was constraints, but once that’s sank it… the world is your oyster init!

Constraints haunt my dreams 
Really, they are my favourite part lol
Must admit… now I understand them it’ll be the one thing I’ll work things from. I like a challenge… this was challenging trying to fit it into my work schedule. But since kids went back to school we’ve been dead.
I’ll be working 16 hours per week next week lol
I’ll fish out one of my ticket closing rules for hotel later, probably much more complicated that needed but it has some good long constraints with a bunch of && and || for good measure 
Dunno what && or || is but I’ll research lol
AND and OR…
I kind of thought the && would be that. || I didn’t have a clue though.
Hmm, what shall I build tomorrow
