How to Reference an Array/Object From Script A Into Script B?

[Karrr 10]

So I have this script

createspikes.sqf

_spikenamepool = [spike1, spike2, spike3, spike4, spike5, spike6, spike7, spike8, spike9, spike10, spike11, spike12];

_spikes = "spikestrip";

_spike1 = _spikenamepool select 0;
_spike1 = _spikes createVehicle [0,0,0];
_spike1 attachTo [player,[0,1.5,0]];


demountstripadd = player addAction ["Place Spike Strip", "demountspikes.sqf"];

player removeAction beginstripadd;
beginstripadd = beginstripadd - 1;

demountspikes.sqf

detach spike1;

player removeAction demountstripadd;
demountstripadd = demountstripadd - 1;

It spawns in correctly and attaches to the player then when I execute demountspikes.sqf it does nothing, I've tried using the array _spike1 the actual object name and everything. Any help is appreciated
