WARNING!!! elevators are hard coded by the looks of it, and only go to specific map index's.( see Elevator Type List ). Some go from level to level on the same map, others go from map to map..
You will need to either save your map/s as the corresponding name/s,or edit the maps.txt file to replace the map/s with your map name/s..
IMPORTANT!! You must remove or re-name the patch000.dat file because it overides anything in the data directory.
First of all, you will need to change the elevstub.frm in your C:\Program Files\Blackisle\Fallout2\data\art\scenery folder for another .frm in order to be able to select the stub to edit it. I suggest the elevstub.frm in my downloads section, but any art will do.. bear in mind that it will be visible in the game, but should be hidden behind a wall if done right..
Build your elevator.
Place a "zselev01" spatial script inside the elevator with a radius of 1 ( so it only triggers when you get in the lift.. ),then place an elevator stub ( scenery tile #1292 )next to the lift.
Select the stub and edit it's properties to suit your map type and elevation number.( bear in mind that the game considers mapper level 1 as elevation 0 and so on )
Your lifts will now work, as long as you have either saved your map as the coresponding name or edited the maps.txt file so the entry for the index number points to your map instead..
If you have NOT saved you map as stated above, then the lifts will send you to the coresponding map named in the Elevator Type List
