if statements

I'm not sure how you write multiple arguement with the if statements: If windows exist then sleep for 1second, click at coordinates, then go to next function.

Here's what I have so first, but doesn't work:

Func CloseHim()
If WinExists("[CLASS:#32770]","") Then
{
WinActivate("[CLASS:#32770]","") ;select and close alarm
sleep(1000)
MouseClick("LEFT", 869, 362, 1)
SMC()
}
Else
   SMC()
EndFunc
