CPU watch and email with AutoHotKey - autohotkey

Question

I'm trying to setup an automatic email if the conditions are meet. I'm trying to watch my cpu load. if pass or drops over a number send a email.
CheckCPULoad:
CoordMode, ToolTip, Screen
SetFormat, float, 0.0
CPULoad := GetCPULoad_Short()
ToolTip, CPULoad = %CPULoad%%, 0 ,%A_ScreenHeight%
return
GetCPULoad_Short()
{
Static IdleTime, Tick
global ProcessorCount
SetBatchLines, -1
OldIdleTime = %IdleTime%
OldTick = %Tick%
VarSetCapacity( IdleTicks,8,0)
DllCall("kernel32.dll\GetSystemTimes", "uint",&IdleTicks, "uint",0, "uint",0)
IdleTime := *(&IdleTicks)
Loop 7
IdleTime += *( &IdleTicks + A_Index ) << ( 8 * A_Index )
Tick := A_TickCount
Return 100 - 0.01*(IdleTime - OldIdleTime)/(Tick - OldTick) / ProcessorCount
}
#############
#IfEqual, CPUload, 0,
#or
if (CPUload = 0)
{
IfWinNotExist Inbox - Email#Email.com - Outlook
return ; Outlook isn't open to the right section, so do nothing.
WinActivate ; Activate the window found by the above command.
Send ^n ; Create new/blank e-mail via Control+N.
WinWaitActive Untitled - Message (HTML)
Send, sentEmailto#help.com
Send {Tab 3} computer has stopped ; Set the subject line.
Send {Tab} more txt. ; etc.
return ; This line serves to finish the hotkey.
}
But I tried with a simple
if (CPULoad = 0)
msgBox testing
and it won't give me a message. why can i get a message box to show. or email to send?

This post got me curious to see if this had been done before and I instantly found a solution posted on the ahkscript forums:
Loop {
If (CPULoad() > 25) ; Assign the Number you want.
; Your EMAIL Code here! If MultiLine Use {...code...}
Sleep 250
}
CPULoad() { ; By SKAN, CD:22-Apr-2014 / MD:05-May-2014. Thanks to ejor, Codeproject: http://goo.gl/epYnkO
Static PIT, PKT, PUT ; http://ahkscript.org/boards/viewtopic.php?p=17166#p17166
IfEqual, PIT,, Return 0, DllCall( "GetSystemTimes", "Int64P",PIT, "Int64P",PKT, "Int64P",PUT )
DllCall( "GetSystemTimes", "Int64P",CIT, "Int64P",CKT, "Int64P",CUT )
, IdleTime := PIT - CIT, KernelTime := PKT - CKT, UserTime := PUT - CUT
, SystemTime := KernelTime + UserTime
Return ( ( SystemTime - IdleTime ) * 100 ) // SystemTime, PIT := CIT, PKT := CKT, PUT := CUT
}
