How do I find the mode in a table?

So basically a mode is the most frequently said value in a table. How would I find that in roblox? Heres a code I found from another post, I can’t seem to get it to work. What am I doing wrong?

Im trying to make a voting system where the person with the most votes is chosen.

This is inside a script:

local mostvotedplr = ""
local voteenabled = false
local playersvoted = {
}

local function countvotes()
	table.sort(playersvoted, function(a, b)
		print(b) -- this doesnt show in output
		mostvotedplr = b
		return a < b
	end)
end

--inside a function
local plr2 = game:GetService("Players"):FindFirstChild(plr)
	if plr2 then
			table.insert(playersvoted, plr) -- plr is a string value
	else
			rs.Warn:FireClient(player, "[server]: this player cannot be found")
	end

--in another function
countvotes()

You should be getting some errors because you can’t do something like workspace < game.

It might help if you filled in the playersvoted table with some example data.
This is the kind of thing I might expect to see for mode:

local votes = {}

local function vote(option)
	votes[option] = votes[option] and votes[option] + 1 or 1
end

local function countVotes()
	local winner = {}
	local bestVal = 0
	
	for k,v in pairs(votes) do
		if v > bestVal then
			winner = {k}
			bestVal = v
		elseif v == bestVal then
			table.insert(winner, k)
		else
			-- lower do nothing
		end
	end
	return winner
end

vote('fred')
vote('fred')
vote('fred')
vote('red')
vote('red')
vote('red')
vote('ed')
vote('ed')
vote('ed')
vote('ed')
vote('cindy')
vote('cindy')
vote('cindy')
vote('cindy')

-- this accounts for ties
for _,winner in ipairs(countVotes()) do
	print(winner)
end

local function GetTableMode(Table)
	local Dictionary = {}
	for _, Value in ipairs(Table) do
		Dictionary[Value] = if Dictionary[Value] then Dictionary[Value] + 1 else 1
	end
	local Array = {}
	for Key, Value in pairs(Dictionary) do
		table.insert(Array, {Key, Value})
	end
	table.sort(Array, function(Left, Right) return Left[2] > Right[2] end)
	return Array[1][1]
end

local Mode = GetTableMode{1, 2, 3, 4, 5, 5, 6, 7, 8, 9}
print(Mode) --5

Before you ask about the function call’s syntax.

If the function has one single argument and this argument is either a literal string or a table constructor, then the parentheses are optional
