Deta Dimmer autoexec.bat: Why isnt alias check_all updating Channel 2 to Channel 3?

Hi
I am having an issue with scripting on a Deta Dimmer
Below is my autoexec.bat contents

startDriver TuyaMCU
tuyaMcu_defWiFiState 4
waitFor MQTTState 1

setChannelType 1 toggle
setChannelType 2 dimmer1000
setChannelType 3 TextField

tuyaMcu_setDimmerRange 100 1003

setChannelLabel 1 "Power"
setChannelLabel 2 "Dimmer"
setChannelLabel 3 "Min Light Dimmer"

linkTuyaMCUOutputToChannel 1 1 1
linkTuyaMCUOutputToChannel 2 2 2
linkTuyaMCUOutputToChannel 3 2 3

alias check_all if $CH2 < $CH3 then setChannel 2 $CH3

addEventHandler OnChannelChange 1 setChannel 201 $CH1
addEventHandler OnChannelChange 2 setChannel 202 $CH2
addEventHandler OnChannelChange 3 setChannel 203 $CH3
addEventHandler OnChannelChange 2 check_all
//addEventHandler OnChannelChange 3 check_all

// On start
addRepeatingEvent 5 1 backlog setChannel 1 $CH201; setChannel 2 $CH202; setChannel 3 $CH203

The issue is that this line does not seem to work
alias check_all if $CH2 < $CH3 then setChannel 2 $CH3
If we assume the value of channel 3 is 100 if I set the slider of Channel 2 to 50
I would think this line would reset it to 100 but it does not seem to run
I know the channel 3 value is text but I still thought it would have worked
What am I missing
Thanks

That's probably because our "if" expects a single token with no spaces as condition, so try:


Added after 31 [seconds]:

we also have up to 64 channels I think
