Adding Text onto Existing Text? [SOLVED]

EDIT: I feel like a idiot because I realised that I just needed a '..' for it to work. Sorry to those who lost braincells due to my stupidity

Hey, I'm trying to make a Discord Webhook that prints stuff to discord and also puts that info on a textlabel in the game, but I really just don't know how to get this to work.

What I tried:

script.Parent.Text = script.Parent.Text + '/n'..player.Name..' joined RBB on '..date.day..'/'..date.month..'/'..date.year..' (Australian Date Format)'

Someone may have already answered this or this is really easy and I'm a idiot, but can someone try to help me figure out how to do this?

Thanks.
