so what am i doing wrong with Fomar0153's script?

any help please

 

[Shaz]

Please enclose your code in code tags so it's more readable, and all of that within spoiler tags for a long script. In this case, better to actually link to the original script.


Which line is line 80?


I bet you've added the script, then loaded a save file that was made before the script was added. Start a new game.

 

[Engr. Adiktuzmiko]

are you trying it out on a saved game? if yes, try it out on a new game...


this is line 80: if @element_uses[id].nil?


so it seems like @element_uses wasn't set-up, which is what happens if you tested this out on a saved game
