[SCRIPT] Adduseitem callback not working?

[zombiehacker595]

need to make an internal name for the chemicals that you add

{
AddUseItemCallback("", "chemical_container_1", "epoxy_container02_1", "pickepoxy", true);
AddUseItemCallback("", "chemical_container_1", "epoxy_container02_2", "pickepoxy", true);
AddUseItemCallback("", "chemical_container_1", "epoxy_container02_3", "pickepoxy", true);
}

void pickepoxy(string &in asItem, string &in asEntity)
{
RemoveItem("chemical_container_1");
GiveItem("chemical_1", "chemical_container_epoxy_1", "", "chemical_container_epoxy.tga", 1.0f);
PlaySoundAtEntity("", "puzzle_acid_success.snt", "Player", 0, false);
AddUseItemCallback("", "chemical_1", "acid_container_1", "pickacid", true);
}

void pickacid(string &in asItem, string &in asEntity)
{
RemoveItem("chemical_container_epoxy_1");
GiveItem("finishedchemical", "chemical_container_full_1", "", "chemical_container_full.tga", 1.0f);
PlaySoundAtEntity("", "puzzle_acid_success.snt", "Player", 0, false);
}
