How can I send a Server script to work on a client server?

Note: Could you try to rephrase your question? My answer is based on what I believe you're trying to say.

Anyways, from what I'm interpreting, you are wondering how to get a ServerScript's features (i.e Functions, Statements, etc.) to show to the clients. With this, you can use RemoteEvents to display information from the Server to the Client. Here's a little example: Main Script

if 1 + 1  == 2 then
game.ReplicatedStorage.RemoteEvent:FireAllClients()
end

LocalScript

game.ReplicatedStorage.RemoteEvent.OnClientEvent:Connect(function()
    print("hi!")
end)

What I did was comunicate to all the clients by firing the RemoteEvent. Upon firing, the clients receive the message, and end up printing "hi!" into the Client's output. You could also replace this with FireClient(). Hopefully this helps, and I'm sorry if I misunderstood your question!
