Asterisk 21.9 Set not setting the variables

Asterisk Asterisk Dialplan
1

Hi, I have very simple execIF testing the ${EXTEN} and then to remove some digits from the start of the number before dialing out.

Here is what i have for the dialplan

exten => _X.,1,Noop(Calls to UK)

 same =>     n,Set(CALLERID(num)=+${CALLERID(num)})

 same =>     n,Noop(extens = ${EXTEN:0:2})

 same =>     n,Set(NEW=${EXTEN})

 same =>     n,ExecIF($["${NEW:0:2}"="00"]?Set(${NEW}=${NEW:2}))

 same =>     n,ExecIF($["${NEW:0:1}"="0"]?Set(${NEW}=${NEW:1}))

 same =>     n,Dial(PJSIP/+${NEW}@peer-1uk)

 same =>     n,Hangup()

Nothing special, I’m getting no errors, and the debug shows its setting it to true and running it, but its not overiding the current value.

Kinda stumped on this, am I making a school boy error?

This should be:

same => n,ExecIF($[“${NEW:0:2}”=“00”]?Set(NEW=${NEW:2}))
