Remote Function Sending a Value over Client to Server?

I'm trying to use a remote function to pass over two player values to be saved to a lead board database. I can't get the remote event to send the values or something, but the code doesn't spit out any errors. Could someone please help me out.

Local Script:

local button = script.Parent
local gui = script.Parent.Parent.Parent
local text = script.Parent.Parent.TextBox
local a = text.Selling

local player = script.Parent.Parent.Parent.Parent.Parent
local stats = player:WaitForChild("LeaderStats")
local b = stats:WaitForChild("Coins")
local c = stats:WaitForChild("Diamonds")

text.Changed:Connect(function()
    b.Value = text.Text
end)

button.MouseButton1Down:Connect(function()
    if b.Value >= a.Value then
        b.Value = b.Value - a.Value
        c.Value = c.Value + a.Value * 1.5
    game.ReplicatedStorage.ServerHandlers.SellEvent:FireServer(player, b, c)
        print(player.Name.."|Diamonds: "..c.Value.."|Coins: "..b.Value)
    end
end)

Server Script:

--[[There is more to this script, but it's unrelated to the problem]]
game.ReplicatedStorage.ServerHandlers.SellEvent.OnServerEvent:Connect(function(player)
    local stats = player:WaitForChild("LeaderStats")
    local b = stats.Coins
    local c = stats.Diamonds

    print(player.Name.."|Diamonds: "..c.Value.."|Coins: "..b.Value)
end)

Currently the script in the prints show me the local stats and the server stats after the trade is completed. I'm not sure what's going on here.
