Respawn tickers GUI- help needed

[goldenfiver 11]

Hi guys, I'm trying to create a respawn tickets system. ( I've tried the vanilla one but it does not work the way I want). I need to find a way to let the players know how many tickets are left at any given time.

I want to create a small box displaying the number of tickets (parameter value). I will really appreciate any help since I don't know where to start (I read the guides and can create a basic GUI element).

Made some progress- this is what I have: 

This is the section in Description.ext : 

class RscTitles
{

class isrtg_respawn_tickets_hud
{

	idd = 23400;
	duration = 20000;
	onLoad = "execVM 'isrtg_scripts\respawn_tickets\isrtg_respawn_tickets_display.sqf';";
		class controlsBackground
		{
			class background_isrtg_respawns: RscPicture
			{
				idc = 5400;
				text = "isrtg_scripts\respawn_tickets\textures\respawn_background.paa";
				x = 61.9 * GUI_GRID_W + GUI_GRID_X;
				y = -5 * GUI_GRID_H + GUI_GRID_Y;
				w = 1.5 * GUI_GRID_W;
				h = 1 * GUI_GRID_H;
			};
		};
		class controls
		{
			class isrtg_respawn_tickets_display: RscText
			{
	
				idc = 23402;
				text = "15"; //--- ToDo: Localize;
				x = 61.9 * GUI_GRID_W + GUI_GRID_X;
				y = -5 * GUI_GRID_H + GUI_GRID_Y;
				w = 1.5 * GUI_GRID_W;
				h = 1 * GUI_GRID_H;
				font = EtelkaNarrowMediumPro;
				//colorBackground[] = {0, 0, 0, 1};
				//colorText[] = {0, 0, 1, 1};
				sizeEx = 0.03;
			};
		};
	};
};

I have no problem displaying this using cutRsc.  What I want to do now is to make 'isrtg_respawn_tickets_display' display the real parameter value of the tickets. I tried using another file to deal with this using the onLoad command. 

This is the file I made: 

		
		while {(str (findDisplay 23400)) != "no display"} do {
			ctrlSetText [23402, format["%1", west_tickets_number]];
		};

This works just fine when used with a normal dialog, but I can't get the same result using cutRsc. Can anyone tell me what I'm doing wrong?
