Help a scrub like me with simple lua?

I need to be able to take a value and constantly add to it. What I'm trying to make is a cinema auto downvoter for all videos up but when another video is posted, it's id goes up by one and I can't skip it if I can't have my script adjust to it. Example;

RunConsoleCommand("cinema_votedown", "1")
RunConsoleCommand("cinema_votedown", "2")
RunConsoleCommand("cinema_votedown", "3")
RunConsoleCommand("cinema_votedown", "4")
RunConsoleCommand("cinema_votedown", "5")

That would downvote the first 5 videos since the client connects to the server but it breaks after 5 and I'm too lazy to add hundreds of RCCs...

Use a loop, lmao.
