Need to add altimeter to HALO jump

[McSpuds 10]

I have searched through so many threads my eyes hurt. Does anybody know how I can add a altimeter to my HALO script?

I would love to use what is in DomiOA but I can never get it to work. Too many pieces and I am not good at coding.

Here is what I am using:

Flagpole code

this addAction["HALO","flagpoleHALO.sqf"];

sqf script

haloed = true;
hintSilent "Click on the map where you'd like to HALO.";
onMapSingleClick "player setPos _pos; [player, 2000] exec 'ca\air2\halo\data\Scripts\HALO_init.sqs';haloed = false;hint 'Close the map and don''t forget to open your chute!'";
waitUntil{!haloed};
onMapSingleClick "";
