Why is the track/ramp unusable

dwarf-fortress

I've constructed a track/ramp in DF v0.34.10, but it shows as "Unusable". I've tried building it the other direction (E/W) several times, but to no avail. How can I build a usable track/ramp in this situation?

Ramps are tricky to get right. In a nutshell, the space below the floor you want the ramp to lead up to can't be open space, it has to be a wall (constructed or natural).

If I'm reading your diagram right (A legend or a prtsc picture would be wonderful), you've got open space on all 4 directions next to your up-ramp. Fill that square in with a constructed wall (the blank spot on the 2nd diagram) and it should work.
