[[SAVED_IP_ADDRESS]] == "undefined" - If Loop using Labels not working

[boozer]

Im trying to setup a way for system to check proxy inside a function.
The proxy is taken from a list.
If the proxy fails i want to restart the loop to go to the beginning and pull new IP

Im using "Label" for a loop

So the logic im using to check to see if the good proxy saved to variable [[SAVED_IP_ADDRESS]]

I use if statement and check for [[SAVED_IP_ADDRESS]] == "undefined" ( meaning proxy check failed)
But it does not catch the failed ip and results in end of thread without loop

[04:58:34] Thread #1 : Failed to get proxy ip

i used variable inspector and it says SAVED_IP_ADDRESS: "undefined"

so shouldnt using [[SAVED_IP_ADDRESS]] == "undefined" be ok?

[selector]

typeof [[VAR]] == 'undefined'
