BIS_fnc_taskAttack -undefined Varible

[1para{god-father} 105]

Getting a error on the BIS_fnc_taskAttack -undefined Varible - can somone please advise where I am going wrong ?

(BIS_fnc_spawnGroup works no problems)

Also should I use BIS_fnc_taskAttack or just use WP to send them in to attack ?

which is best ?

_ambush1 = createmarker ["AMBUSH1",getpos _vehicleambush];
_ambush1 setmarkershape "ELLIPSE";
_ambush1 setmarkersize [150,150];
_ambush1 setMarkerColor "ColorRed";
_grp = [ _positionToSpawnIn, _side, _enemyCount] call BIS_fnc_spawnGroup;

_null = [_grp,(getMarkerPos _ambush1)] call BIS_fnc_taskAttack;

if you use this, you can see the exact details of the BIS_fnc_taskAttack.

but if i remember correctly, it is just a set of SAD waypoints. (search and destroy)
