Sounds and messages

[giacomo9]

I've got a script:

void Scared_9(string &in asParent, string &in asChild, int alState)
{
SetEntityActive("DeadFour_9", true);
SetEntityActive("DeadFour_10", true);
GiveSanityDamage(99, true);
PlaySoundAtEntity("", "24_iron_maiden.snt", "Scary_9", 0, false);
}

After activation this script, I would like to:
1) The player saw the message on the screen (for example, "RUN!")
2) Two seconds after activation of the script there was a sound (different than in script above)
How to do it?

I'm sorry if somewhere there is a spelling mistake, charms of use google translator xD
