Entity Activate/Deactivate?

[Bonehead]

this is what I had... and now it's not working at all..

void OnPickup(string &in asEntity, string &in type)
{
SetEntityActive("armour_nice_complete_8", true);
SetEntityActive("armour_nice_complete_7", true);
SetEntityActive("armour_nice_complete_6", false);
SetEntityActive("armour_nice_complete_5", false);
PlaySoundAtEntity("armour_nice_complete_8", "", 0, false);
PlaySoundAtEntity("armour_nice_complete_7", "", 0, false);
}
