voting system with map

--[[
NOTES:
if you want to use this exact script make sure there are 3 parts in workspace
each part should be nammed Button1, Button2 and Button3
each part should have a surfacegui with a textlabel

you also need a folder named Maps in replicatedstorage
put at least 3 maps there or else death
create a model in workspace named "Structures"

otherwise if you know what you're doing go apes**t i guess
]]

Button1 = game.workspace.Button1
Button2 = game.workspace.Button2
Button3 = game.workspace.Button3

--[[
if you dont understand what this does
its a pre-set function before the while true do
it randomly picks the maps in the maps folder
it keeps randomly picking the maps until all of the map variables have different map numbers
it puts them into the table called "tablemap" and then returns the table
which means if you use function obtainmap() it would have the value of the table

hope this helps lmao
