i would be grateful if some one who knows what they are doing can help with either diagrams or a very detailed explination
Thank you for your time

Answer 1

See http://www.handymanwire.com/articles/3wayswitch.html

They have diagrams for several different circuits there with physical sketches also

Answer 2

As I read it, you have 1-way switching working on the lights and you now want to convert it to 2-way for each floor.

OK,
For your 1-way switching you go in at Common and off at L2.
Get that working....

Run your 3-core+e from switch a to switch b.
For 2-way; make these changes.
IN at L1, off at L2 and connect together (using 3-c&e)
Common a to common b,
L1a to L2b and
L2a to L1b
Sleeve all conductors with Brown.

Label the inside of each switch to remind yourself and anyone else that there are two different circuits in the switch...

Answer 3

You've had some pretty good answers already, but really you do need to see a diagram it helps to make sense of it.

Rather than try to explain it to you, have a look here.
