I just started tinkering with Plus! plugins today and I'm writing a ping function,  my side pings the other, the other responds then I want to report the MS it took to respond, but when I try to do math that part just doesn't respond then but if I take the math out it works. Here is what the section looks like.

If sContactName <> MyUserName Then
     PingDelayEnd = GetTickCount
     CurrentPing = False
     PingTime = (PingDelayEnd - PingDelayStart)
     sTextToSend = "Ping Time: 9[" & PingTime & "ms]"
     sText = ""
     ReceiveNotify = True
     Exit Function
Else
     Exit Function
End If
