Is this not working because of "isServer" in my script?

[BEAKSBY 11]

When I test on LAN the joining player can create the tank, but when it calls the paradroptank function the parachute does not deploy like it is supposed to. It only deploys for the player hosting the game.

This is the init.sqf that preloads a player addAction command to execute the ArmorDrop.sqf that then calls the the KK_fnc_paraDropTank at the top of the init.

Createcenter EAST;
Createcenter WEST;
WEST setFriend [EAST,0];
EAST setFriend [WEST,0];

[west, "WEST1"] call BIS_fnc_addRespawnInventory;
[west, "WEST2"] call BIS_fnc_addRespawnInventory;
[west, "WEST3"] call BIS_fnc_addRespawnInventory;
[east, "EAST1"] call BIS_fnc_addRespawnInventory;
[east, "EAST2"] call BIS_fnc_addRespawnInventory;
[east, "EAST3"] call BIS_fnc_addRespawnInventory;
if (sector1 getVariable 'owner' == WEST) then {[west, "sector1"] call BIS_fnc_addRespawnPosition}; 
// [west, "Sector2"] call BIS_fnc_addRespawnPosition; 
[west,[1685,5640,50]] call BIS_fnc_addRespawnPosition; 
// [getPos player, WEST, 5] call BIS_fnc_spawnGroup;

// To use the script you need to spawn a tank 150m or more above the ground and pass tank object reference to the script. 
// For example (should be executed on the server side):

    }];   
};  

This is the ArmorDrop.sqf that calls on the KK_fnc_paraDropTank from the top of the init.sqf:

_tank = "B_MBT_01_TUSK_F" createVehicle [0,0,0];
_tank setDir random 360;

_pos  = screenToWorld [0.5,0.5];// land position 
if (!isnull cursortarget) then { _pos = getpos cursortarget};// building / object position

//Drop smoke & Chemlight & Flare
_smoke = "SmokeShellGreen" createVehicle [(_pos select 0), (_pos select 1), 0]; 
_chemlight = "Chemlight_green" createVehicle [(_pos select 0), (_pos select 1), 0];
_flare = "FlareGreen_F" createVehicle [(_pos select 0), (_pos select 1), 0];

_tank setPos [(_pos select 0), (_pos select 1), 150];
_tank call KK_fnc_paraDropTank;

hint format["Incoming Armor at %1",(position _pos)];

// Delete smoke and light
waitUntil {getPos _tank select 2 < 5};
deleteVehicle _smoke;
deleteVehicle _chemlight;
deleteVehicle _flare;

Or is something wrong with the order? Should I be including all this in the init.sqf too or create separate .sqf scripts? These addActions will be called frequently in the MP game.
