AHK, how to capture Rbutton in loop - loops

Question

Could someone help me understand how to capture Rbutton in Loop?
The idea is when I click GUI button its activate loop and waiting for some time for example 15 sec until RButton will be clicked, if loop detects that RBUtton been doubleclicked, should show me msg box
w::SetTimer Test, 5000
Test:
Loop { ; waiting when RButton will be clicked
Keywait,RButton
A := GetKeyState("Rbutton","P")
if (!%A%) {
MsgBox, this part should continue and wait for RButton do nothing and continue to wait
} else if (%A%) {
MsgBox, you clicked double RButton
Send, this is text
break
}
}
Msgbox end of script
SetTimer Test, Off
Return

My idea:
Use While loop as timer, ie, while within duration (eg 15 secs), keep checking status of double right button. If criteria met within duration, break the loop and show message box.
Use SetTimer and GetKeyState to constantly check and update number of right button clicked.
Note to below script. It is assumed that when GUI is clicked, DetectDoubleClick() will be fired.
Counter_RButton := 0
SecondsToWait := 15
DetectDoubleClick()
{
Global Counter_RButton
Now := A_TickCount
End := A_TickCount + (SecondsToWait * 1000)
SetTimer, CaptureRButton, 150
While (End >= Now)
{
if (Counter_RButton = 2)
{
Counter_RButton := 0
MsgBox,,,Double RButton Detected!
break
}
Now := A_TickCount
}
SetTimer, CaptureRButton, Off
return
}
CaptureRButton:
ButtonIsDown := GetKeyState("RButton")
If ButtonIsDown
Counter_RButton := Counter_RButton + 1
Exit
