Where did you learn to Script? Any suggestions?

I need somewhere to learn Lua, I have all basic skills, but many of it still doesn't make sence.

I personally learned Lua from LearnXinYMinutes, and then learned all of Roblox's OOP and event-driven idioms from the Roblox Wiki. All of the specific features of the Lua language can be found in the Lua Reference Manual, and a lot of advanced usages and concepts can be found in the Lua-users Wiki
