Weid Error in Yanfly script

The "Skill Equip System" has an unusual error on one line. I think it says a class doesn't exist or something.
This is the line it's having problems with:

class Window_EquipSkillData < Window_LearnData

Am I missing something? Do I need another script?

Well, what does the error message say? It might be a missing end above it, or it might be that you don't have whatever script defines the Window_LearnData class, but I can't say for sure without seeing the error message.

Turns out I just needed the Skill Overhaul script.
But I have a new problem. I installed the menu overhaul and I get this error about the reserve party script whenever I open the menu (See attachment)
The particular line it refers to is this:

Code: [Select]

    @command_window = @command_window.class.new(width, c)

[/s]

EDIT:
I found the patch but I get this error:

undefined method 'refresh' for class 'Window_ReDuxMenuStatus'

I assume it has something to do with this script:

Yanfly Engine RD - Scene Status ReDux

Maybe because you are using the ReDux scripts, which Yanfly says probably aren't compatible with the new Melody scripts. I believe it is said on most all of the new scripts.

So there's nothing I can do except delete one of the scripts? I don't see how they conflict...

Actually, I think it has more to do with Scene Menu Redux, but it would probably be best to switch over to Melody anyways.

So I'm assuming I'll need to give up bios for compatibility?

You can incorporate Bios into the menu using other custom Menu screen scripts. Like Aindra's Custom Lists and Pages. I also know that Jet is working on a Menu Scene maker script that you can visually make the screen in a project and it will output the script to create it. I don't know when it will be done... he had me test an early version. My mistake, he's released his Window Maker already

What does 'Refresh' even do anyway? I've found it in both scripts but I don't understand...

Refresh is a method often used to clear and redraw the contents of bitmaps and sprites in a class. It is first erased to prevent overlapping content. (Erases and draws stuff on the window)
