''''^ They will NOT be able to get up from the bottem to the second from the bottem. That is because in order for ramps to work, they have to be placed next to a wall and they can only let a dwarf go up in the direction of the wall.

__________/ For reference, the ramps/channels circled in yellow stopped working because you dug out the wall behind them.
To work, ramps need to be going from a floor, up onto a floor on top of a wall/unmined earth. They can't do up onto just a floor with empty space beneath it.
Example side view (forgive the awful diagram):Code: [Select]

...would be fine (where _ is floor, / is your ramp and O is a wall or unmined earth).
Whereas:Code: [Select]

...would not be fine (where you've mined out the earth under the upper floor), and your ramp will cease working.
Hope that helps!
Edit: hang on, that doesn't explain why your green-circled ramps are working fine. Hmm. My explanation may be flawed.
I see your pics and I perfectly get it why the ramps are not "working".
See, if you build a ramp - to use it moving up the ramp - dwarf needs to walk on the ramp tile (z-1 level) and then move onto a tile that has wall underneath it (z level)
In other words - for ramp to work, there must be wall tile next to it and right above that wall tile there must be floor tile. Look at your pics again - that's not the case. You either have Wall/Wall, Floor/Floor or Wall(z)/Floor(z-1). What you need is Floor(z)/Wall(z-1).
To walk down the ramp it's the same - stand on a floor tile that is placed on a wall tile (z) and then walk on the ramp (z-1).
Also - you may be wondering why ramps marked with green work. The fact is - they don't, only 1 on each side is working - the one on the left (diagonally you have a Floor tile, then Wall one level under it).
Hopes this helps, it's really recommended to get to know how ramps work, especially now that channeling creates a ramp and you will end up with some one way or another.
With Armoks Praises I Fixed It.The stair thing... that's covered in the wiki. It is a bit confusing though I suppose.
For Future Reference:
If you Build Stairs going Up, you then need to move the Camera Up, and Build Stairs going Down, on TOP of the Stairs going Up.
I still have NO Idea why the Channels wont Work, but Screw It. :P
Hard for me to say anything about what was built in there, since I don't get a really clear picture from your description.
Would you kindly build that setup you say should be working and yet it wasn't working and post screenshots of it?
Ramps and walls can be built, floors channeled, and channels floored, so it shouldn't really devastate any of your current work.

X...XIf you have exactly the same layout of floors and walls on both levels - that won't work.I think I see. It doesnt make much sense, but I think I get it :)
Look, your "green" working ramps are actually:
z-1Code: [Select]XXXXX
X▼▼▼X
....X
z-2Code: [Select]XXXXX
X▲▲▲X
X...X
Notice the bottom-left tile. It's "." on z-1 and "X" on z-2 - thus that one ramp on the left is working.
