When I get the tool I want through a script, it shows no icon even though there is normally and it shows the following error:

inputOrder[i] does not exist. You’re essentially doing nil["tool"], which throws the error.

So how do I fix it? Do I replace something or remove it entirely?

Just check if value is nil before indexing it.

#5

Could you please edit the part that is broken and send it? I don’t understand.

#6

I’m not able to edit it off the bat because I don’t have the full context.

#7

It’s a script for a custom hotbar however the icon won’t show up in the tool slot. I just want to get the icon showing. The hotbar is functional.

#8

Do you know how to fix it so it shows the icon of the tool?
