Why won't my RemoteEvent send the correct args?

Basically I'm designing a hotel-like system where it sends a message to the server and then to all players that a room has been taken. It works but only for the first button, and I can't figure out how to tell the server which button was pressed.

Localscript:

r201.MouseButton1Down:Connect(function()
        if roombought == false then
            roombought = true
            rt:FireServer(r201)
        elseif roombought == true then
            r201.Text = "X"
        end
    end)
    r202.MouseButton1Down:Connect(function()
        if roombought == false then
            roombought = true
            rt:FireServer(r202)
        elseif roombought == true then
            r202.Text = "X"
        end
    end)
    r301.MouseButton1Down:Connect(function()
        if roombought == false then
            roombought = true
            rt:FireServer(r301)
        elseif roombought == true then
            r301.Text = "X"
        end
    end)
    r302.MouseButton1Down:Connect(function()
        if roombought == false then
            roombought = true
            rt:FireServer(r302)
        elseif roombought == true then
            r302.Text = "X"
        end
    end)

ServerScript:

rt.OnServerEvent:connect(function(player, r201,r202,r301,r302)
    print "testserver"
    if r201 then
        local tag = Instance.new("StringValue")
        tag.Name = "StringValue"
        tag.Parent = r201
        rtc:FireAllClients()
    end
    if r202 then
        local tag = Instance.new("StringValue")
        tag.Name = "StringValue"
        tag.Parent = r202
        rtc:FireAllClients()
    end
    if r301 then
        local tag = Instance.new("StringValue")
        tag.Name = "StringValue"
        tag.Parent = r301
        rtc:FireAllClients()
    end
    if r302 then
        local tag = Instance.new("StringValue")
        tag.Name = "StringValue"
        tag.Parent = r302
        rtc:FireAllClients()
    end
end)

I'm trying to tell the serverscript via arguments (which I assume I'm using wrong) which room was bought by putting the value in the parenthesis of "fireserver" in the localscript. Then I'm checking to see if it was indeed put in the arguments, which should fire the correct part of the serverscript, which then sends it to another localscript (thats how it's supposed to work in my head, anyways). Like I said, the 1st button works totally fine and when a 2nd player presses the 2nd button, it too works. But if you skip one the localscript doesn't fire to the correct part of the serverscript.

That may have been super confusing, but any and all help would be appreciated!
