How would I remove a string from a Dictionary inside another Dictionary

[misty chasm]

Or its just a table idk the difference that much

Like ts

local Tuff = {}
Tuff.a = {"apple", "banana"}
Tuff.b = {"apple", "banana"}```

wym

local tuff = {
    coolStuff = {
        colour = "Red",
        number = 5
    }
}

do u mean like how to remove colour

[misty chasm]

wait

how would I remove apple from Tuff.a

[misty chasm]

no

[undone fern]

table.remove(Tuff.a,1)

or you can use a loop

[misty chasm]

what if its not ordered and I don't know the order

[undone fern]

for loop

[misty chasm]

like ts?

for i, v in pairs(tuff.a) do
    if v == "apple" then
        table.remove(v)
    end
end```

or is that wrong

[undone fern]

no wait lemme fix

for i, v in Tuff.a do
    if v == "apple" then
        table.remove(Tuff.a, i)
    end
end

[misty chasm]

it says attempt it itterate over a string

[undone fern]

are you sure

it work for me on studio

local Tuff = {}
Tuff.a = {"apple", "banana"}
Tuff.b = {"apple", "banana"}


for i, v in (Tuff.a) do
    if v == "apple" then
        table.remove(Tuff.a, i)
    end
end

[misty chasm]

alright I'll send you my actual script

local Remote = game.ReplicatedStorage:WaitForChild("VoteRemote")

local Poll = {}
Poll.Single = {}
Poll.Double = {}

Remote.OnServerEvent:Connect(function(plr, Vote)
    if Vote == "Single" then
        Poll.Single = plr.Name
        for i, v in Poll.Single do
            if v == plr.Name then
                table.remove(Poll.Single, i)
            end
        end
        print(Poll)
    elseif Vote == "Double" then
        Poll.Double = plr.Name
        for i, v in Poll.Single do
            if v == plr.Name then
                table.remove(Poll.Single, i)
            end
        end
        print(Poll)
    end
end)```
I don't think this is the most efficient way to do a poll but I'd want to do it myself

[undone fern]

whats the exact error

[misty chasm]

ServerScriptService.Voting:18: attempt to iterate over a string value - Server -

[undone fern]

its because your making Poll.Single a string

not an array that that the for loop can use
