so my script has multiple keys you cold press to change different things such as ctype, tmp etc. but after adding(into the script not in-game) my third key the whole script stops working how can I fix this problem.

Also I would like to make one of my elements to always have the ctype of acmn , how can I do that.

Ok but the script is not done but its about nano-tech it uses some elements from  the exotic chemistry but modfied+ this is my third day with lua(yes I am a beginner) here it is:

has anyone considered helping me?

I understand no. two but I don't understand number one.

thx btw

Also I would like to make one of my elements to always have the ctype of acmn , how can I do that.

My Idea is to have nanite swarm clouds capable of regenerating, attacking, activating electronics etc... also have you seen my dust (try to put it on top of any solid).
