Can using a Laudanium call a callback?

[Hardarm]

Hi. Can someone call a callback using a laudanium? (obviously to myself);
Just using a normal laudanium.
here's the part of the code:

Code: (Select All)

void fade1(string &in asTimer)
{
SetEntityPlayerInteractCallback("potion_health_1", "TakeIt", true);
FadeIn(1.0);
StartPlayerLookAt("potion_health_1", 10, 1, "");
SetMessage("Global", "Hint02", 4);
SetPlayerActive(true);
}

void TakeIt(string &in asEntity)
{
SetMessage("Global", "Hint03", 3);
SetEntityActive("rock_debris_brown01_1", true);
SetEntityActive("rock_debris_brown02_1", true);
StartScreenShake(0.3, 2, 0.5, 0.5);
PlaySoundAtEntity("", "break_stairs.snt", "ScriptArea_4", 0, false);
AddUseItemCallback("", "potion_health_1", "Player", "fade2", false);
}

void fade2(string &in asItem, string &in asEntity)
{
ExitInventory();
SetInventoryDisabled(true);
FadeOut(2.0);
AddTimer("", 4, "fade3");
}

I tried this, map does start, but fade2 doesn't work. help please?
