I don't understand scripts and probably never will lol. I urgently need help though.
I have a building which needs to be open downstairs but not upstairs. I can lock the doors on external doors, which means i can lock the upstairs patio doors yet still keep one downstairs door open, but not internal and need a way of stopping people entering the upstairs rooms. I can't put a new script in the building apparently and dont want to change it, so what I need is a sort of barrier with a script that allows group members to go past this barrier, but not members without the tag.
Is there a way of doing this?
I tried looking for a solution but honestly don't know where to start

Please be gentle with me lol, Im still learning.
