(ABANDONED)Need help with "if" functions...

[Statyk]

Okay, I KNOW I'm doing this wrong, but I need some pointers on the "if" function. Here's my script:
//_______________________________

void OnStart()
{
AddEntityCollideCallback("Player", "warnarea", "warn_func", false, 0);
}

void warn_func(string &in asParent, string &in asChild, int alState)
{
GetLocalVarString("jacket_1");
{
if(&in asEntity == true)
{
SetMessage("ScreenMessages", "warningmessage", 3);
}
if(&in asEntity == false)
{
SetMessage("ScreenMessages", "none", 1);
}
}
}

//__________________

The problem is what is in the parenthesis after the "if"s I don't know what I should title it. The thing I want it to do is when I walk into an area, if the "jacket_1" is active, the message from "if(&in asEntity == true)" tells me it needs to be gone. but if the jacket is inactive, the message does not display.
