How are you getting "force"

Everything from the game requires getting it from the game.global (unless sent through an event ie. gui events send the element)

local force = game.forces["name-of-force"]

Thank you... I didn't understand what a force was in the context of this game. I thought it was ...

Can't get this to work. In-game it tells me "attempt to index global 'force' (a nil value)"

Please help. I'm going to be uploading it to the mod portal asap. I know a lot of people who want this on my friends list.
