Welcome to these Forums! But have a little patience -- only a couple of hours is a little soon to "bump" something.
In response to @Patchy in Post 3, I don't think there's any need to post a drawing, and I assume your origin is set by UCS, not by Elevation, because of the X and Y values. If I understand correctly that you want the World Coordinate System Z coordinate, when you're in some non-World Coordinate System:
For something like Text such as in your LIST command in the image, the entity data always report in World Coordinates. So you can do this:
(cdr (assoc 10 (entget (car (entsel)))))
which will give you the Insertion Point in WCS units for Text, Mtext, Blocks, Xrefs, the start point of a Line or Polyline, the center of a Circle or Arc or Ellipse, etc. Some other entity types may require a different number than 10 for what you're after.
For picking a point rather than LISTing something [your "click on a level" wording], you can (trans)late the result from current to World coordinates:
(trans (getpoint) 1 0)
You can add a prompt to either of those [see those functions in Help]. Either will give you all three XYZ coordinates in WCS units. If perhaps you want the XY in UCS and only the Z in WCS, that could be done. If you want to know only the Z coordinate, that can also be done.
