Tycoon, inpairs help, ideas? [SOLVED]

function onTouched(hit)
    local check = hit.Parent:FindFirstChild("Humanoid")
        if check ~= nil then
            local plr = game.Players:FindFirstChild(hit.Parent.Name)
            if plr.Name == game.Workspace.Blue.Configuration.Owner.Value then
                if plr.leaderstats.Cash.Value >= 250 then
                for _, Wall in ipairs(game.Workspace.Blue.Walls:GetChildren()) do
                        if Wall:IsA("BasePart") then 
                         Wall.Transparency = 0
                      end 
                   end
                plr.leaderstats.Cash.Value = plr.leaderstats.Cash.Value - 250
                script.Parent:Destroy()
            end
        end
    end
end
script.Parent.Touched:connect(onTouched)

What this does is it detects when a Humanoid touches it then it finds the player from the humanoid. And then if the player matches the owner of the tycoon it checks if the player has enough money to buy the walls. But here's my problem is it only changes one of the walls transparency to 0. Any help is appreciated.
