Why is this not working?!

Why is this not working? I put the script into serverscriptservice and http service is enabled What's wrong, or is it the module name or something?

Require (mymoduleid)

Modules: http://wiki.roblox.com/index.php?title=API:Class/ModuleScript

Require: http://wiki.roblox.com/index.php?title=Function_dump/Functions_specific_to_ROBLOX#require

My best advice would be to know how these two components work before attempting to use them. If you have any questions on how to use them or how they work, feel free to ask. But I'm afraid this question is way too broad, and lacking critical information required to answer it properly.
