How combine two Items?

[Shives]

Oh I forgot to
Post my Script


void Expoxy(string &in asItemA, string &in asItemB)
{
PlayGuiSound("12_epoxy_fill.snt", 1.0f);
RemoveItem("Chemie");
RemoveItem("Flasche");
GiveItem("Spreng", "chemical_container_half", "", "chemical_container_half.tga", 1);
}

void OnGameStart()
{
AddCombineCallback("", "Flasche", "Chemie", "Expoxy", false);
}
