Variables in MikroTik?

Question

Mikrotik

Hello. In the DHCP ALert script, I create a global variable :global var1;and assign it the found MAC address :set var1 $"mac-address". Then I call the script that contains ( see below )

:global var1;
:global var2;
:set var2 ([/system ssh-exec address=адрес user=пользователь command="команда $var1" as-value]->"output");

.
The script has the following rights ( see below )

In this case, the value of the variable var2remains empty. But if I create a global variable in the console :global var1, assign it a MAC address ( absolutely the same ), then the variable var2will contain the value returned by the SSH server.

In both cases, in ( see below )

, the variable var1contains the same value of the MAC address , and the same value of the variable is sent to the server.

Help to understand please.
