Is this the right way to set a global variable to be based on a players name?

Basically I have a stringvalue of the players name So would I just go

_G.script.Parent.PlayerName.Value = 'StuffHere'

That's what I have so far but I won't be able to test until the entire script is finished so I need to know now if it'd work or if there's something else I need to do.

EDIT: To clarify what exactly I have so far

Structure Player - Script, PlayerName stringvalue

script

_G.script.Parent.PlayerName.Value={
bank={},
checks={bankchanged=false,inventorychanged=false,inventorylimitreached=false,skilling=false,stopanim=false},
inventory={},
resources={},
skills={cooking={level=1,xp=0},fishing={level=1,xp=0}}
} --All the things that will be saved.
