How do I collect all the columns in google spreadsheet?

So, I’m currently trying to make a discord bot database that can ban people with a reason for ban in our roblox game.

Everything works, but I just can’t seem to get another column. Which is the “reason” for ban.

I’ve tried to get all the data in the google spreadsheet, but it just keep saying an error.

for _,player in pairs(game.Players:GetChildren()) do
		local ReValue = globalDatabaseGlobal:GetAsync(player.UserId)
		local banTable = ReValue:GetAsync(player.UserId.."reason")
local reason = banTable[1]
		if ReValue == true then
			player:Kick("You've been banned by Console for breaking ROBLOX's TOS. Reason: "..reason[1]) 
		end
	end

Anything helps. I just wanna know how to get another column like B,C etc.
