get part of address

[Frank68]

What are you trying to do?
See this https://forum.logicmachine.net/showthrea...7#pid28967

automatically I would like to read the last part of the group address, for example /20 and then write, depending on the case, in another virtual tag that always ends with /20 if I could break down the script to be able to read the last part of the group address it would be perfect.

Thank you
