Who can help me figure out the script for Mikrotik?

Question

Mikrotik

I can’t understand why the script doesn’t work like that, I’ve been fighting with it for 2 days already,
an example of a script

spoiler

:local MAC
:set $MAC XX:XX:XX:XX:XX
:local WIFI
:set $WIFI 0
:if ([/caps-man registration-table find mac-address=$MAC] != "" and $WIFI = 0) do={[/tool fetch url="https://api.telegram.org/botbotTOKEN/sendmessage?c..." keep-result=no] and [:set $WIFI 24]};
:if ([/caps-man registration-table find mac-address=$MAC] = "" and $WIFI != 0) do={[:set $WIFI ($WiFi-1)]};
:if ($WIFI=1) do={/tool fetch url="https://api.telegram.org/botTOKEN/sendmessage?chat..."};

I can’t find where I messed up, in theory, the script should check the poppy in the table, if it is there, then send 1 message to telegram, if there is nothing to send, if it appears, then send 1 message and the next should be sent only when it turns off, but now he only spamming about the fact that the poppy is online.

Answer 1

The local variables in your case exist only while the script is running. In order for the variable not to be destroyed after the script is processed, create a global variable. In your case it should be
:global WIFI
