Counter for a script.

For the past two hours I've been trying to declare a variable that would count how many times the LogiMachine has not reached the Internet.

If I don't declare the variable PingFailure, I get to following error message:

Resident script:17: attempt to perform arithmetic on local 'PingFailure' (a nil value)

If I do declare it, it never counts above 1 as it resets itself each time I carry out the script.  How is this done, I've searched this forum and the Internet?



function ping(ip)
  local res = os.execute('ping -c 2 -W 5 ' .. ip)
  return res == 0
end

local PingFailure = 0

ping = ping('google.com')

if ping then
  log('INTERNET connected')
  log(ping)
 
else
  log('INTERNET disconnected')
  log(ping)
  PingFailure = PingFailure + 1
end 

log(PingFailure)


I look forward to hearing from you.

Cheers!
Martin

You should use next construcion:

Code:
if not PingFailure then
  PingFailure = 0
end
In this situation it'll refresh only when you restart script.
