Drawing Icon on trigger pos.

I am running a custom mission. 

I am trying to make a simple change that is proving to be a tad more complex than I'd thought. The simple short version is that I am simply trying to draw a (custom) 2d icon on the player map and gps with drawicon and using getmissionpath "\folder\genericimage.paa", and then update the position of that icon on a set interval. However, accessing the position of the bonuz zone is proving to be a challenge. 

 

The mission is a custom sector control mission. 

 

The mission selects either a random trigger or one chosen by name by the host. That trigger serves as the main AO. Inside, there is another trigger that acts as a moving zone. Here is how the zones are created:

	made for Northup

	PURPOSE: Creates a capturable zone which different teams can fight over and gain points in accordance
	to each team's relative presence.

	INSTALLATION: Ensure the accompanying functions are inside a "functions" folder in
	your mission directory. Also, ensure the included functions.hpp and description.ext files are placed in
	your mission root directory.

	USAGE: call the function on SERVER at any time while mission is running.
	
	PARAMETERS:
	
	triggerName: String
	triggerPos: Array of numbers or Object
	triggerSize: Array of numbers
	triggerAngle: Number
	triggerShape: Boolean
	triggerInnerSize: Array of numbers
	triggerInnerPoints: Number
	triggerRefresh: Number
	triggerIcons: Array of strings
	triggerBackground: String
	triggerOpacity: Number
	
	EXAMPLE: 
	["ALP_area_1", [0,0,0], [50,50,-1], 0, false, [25,25,-1], 1, 60, ["flag_NATO", "flag_CSAT", "flag_AAF", "b_installation"], "SolidBorder", 0.75] call ALP_fnc_sectorCreate;

_ALP_triggerRefresh = param [7, 60, [0]]; // NUMBER, (Optional, default 60) - number of seconds before trigger refreshes and awards points according to each faction's relative strength

However, there isn't an actual position to grab there, since the bonus zone movement is handled in the sector manager:

I have tried to grab the pos from _ALP_triggerBonusNewPos_X and _ALP_triggerBonusNewPos_Y,0 to no avail. 
I wrote a script that is executed on initplayerlocal.ini:

Spoiler 



params ["_ALP_trigger", "_ALP_triggerName", "_ALP_triggerInnerPoints", "_ALP_triggerRefresh"];
ALP_triggerArea = triggerArea _ALP_trigger;
_ALP_triggerBonusArea = triggerArea _ALP_triggerBonus;
_ALP_triggerPos = getPos _ALP_trigger;

drawIcon ["\a3\3den\data\cfgmarkers\flags\us_ca.paa", [1,1,1,1],  _ALP_triggerPos, 20, 20, 0, "", 2, 0.03, "TahomaB", "right"]; 
while {true} do {
  _ALP_triggerPos = getPos _ALP_trigger;
  drawIcon ["\a3\3den\data\cfgmarkers\flags\us_ca.paa", [1,1,1,1],  _ALP_triggerPos, 20, 20, 0, "", 2, 0.03, "TahomaB", "right"]; 
  sleep 1;
};


 

I'm sure I am doing it all wrong. If anyone has any insight, please let me know.
