Make a player hungry/thirsty?

[DangerRuss]

I have a script Im trying to implement. When the player uses the item it will cause them to become very thirsty/hungry. Everything about the script works as it should except that part and Im not sure what Im doing wrong.

if (random(_infectionChance) < 1) then {
         
            dayz_lastDrink = time;
            dayz_thirst = 1;
 
            dayz_lastMeal = time;
            dayz_hunger = 1;
            
            player setVariable ["messing",[dayz_hunger,dayz_thirst],true];
            
            //Ensure Control is visible
            _display = uiNamespace getVariable 'DAYZ_GUI_display';
            (_display displayCtrl 1301) ctrlShow true;

          } else {
