I can't code and am trying to figure out how to make another inventory, help.

If you can't code, why are you using a program that requires you to code in order to create anything?
I suggest you look for some of the many programming guides available on the WWW and start reading and experimenting.
Try PYTHON as a start and when you feel confident, move on and eventually come back here. There is also SCRATCH which is a good starter to programming.
Also you could download the desktop version and work through the tutorial. That will give a realistic idea as to if you want to program at all.
Good luck
