I guess you can, but you'll probably get the same errors. Computers aren't magical, if you write the same code/do the same things you'll get the same results.
Uh. I don't know what you're asking.
Your error message starts like this:
Code:
Message: undefined method 'length' for nil:NilClass
PItem_Bag:101:in 'Quantity'
So you're going to have to look at line 101, work out what thing is unexpectedly nil (if the code says
something.length then it will probably be the something). And then work out how to prevent it being nil.
That probably means finding the code in Essentials that runs when the bag is opened, and seeing if it does something like:
Code:
if somethingElse==nil
somethingElse=...
end
And copying that somewhere useful. Possibly just above line 101.
somethingElse may or may not have the same name as
something.
That's the quick description of the quick hack to fix the problem.
