How to find a variable inside of ctrlText?

[gr1D- 10]

I'm wondering how to find a variable (A good example is %s inside of systemChat, like systemChat ["Weapon Created: %s",_weapon]) inside of the string retrieved from ctrlText.

I'm making a script for admins where you can spawn items in via Chat, like /spawn <insert classname>. I'm using a function made by Killzone Kid to find if the text /spawn is in the string, but I'm not sure how to find what is after /spawn.

Here is my code so far:

KK_fnc_inString = {
   /*
   Author: Killzone_Kid

   Description:
   Find a string within a string (case insensitive)

   Parameter(s):
   _this select 0: <string> string to be found
   _this select 1: <string> string to search in

   Returns:
   Boolean (true when string is found)

   How to use:
   _found = ["needle", "Needle in Haystack"] call KK_fnc_inString;
   */

   private ["_needle","_haystack","_needleLen","_hay","_found"];
   _needle = [_this, 0, "", [""]] call BIS_fnc_param;
   _haystack = toArray ([_this, 1, "", [""]] call BIS_fnc_param);
   _needleLen = count toArray _needle;
   _hay = +_haystack;
   _hay resize _needleLen;
   _found = false;
   for "_i" from _needleLen to count _haystack do {
       if (toString _hay == _needle) exitWith {_found = true};
       _hay set [_needleLen, _haystack select _i];
       _hay set [0, "x"];
       _hay = _hay - ["x"]
   };
   _found
};

while {true} do 
{
waitUntil {!isNull (findDisplay 24)};
disableSerialization;

_display = findDisplay 24;
if !(isNull _display) then
{
        _textFind = _found = ["/spawn ", _text] call KK_fnc_inString;
        _classname = ??? (This is where I don't know what to do.)
        if (_textFind) then
	{
	     private ["_object","_qty"];
		_object = createVehicle ["WeaponHolder",position player,[],0,"CAN_COLLIDE"];
		_object setVariable ["permaLoot",true];
		_qty=1;_object addWeaponCargoGlobal [_classname,1];
            systemChat ["Item Given: %s",_classname];
            player selectWeapon _classname;
     (_display) closeDisplay 0;
	};

Any help would be appreciated.
