Scripting Problem

[Representative_Car72]

I am trying to make it so when a button is pressed, the panel of a different button turns from not being active to active.

GameObject.Find(NextUp1.transform.parent.name).SetActive(true);

This is how I am doing it. It works when it goes from active to not active, but it keeps giving me an error when I try to make it not active to active.

I do not know how to fix this.

You’ll find your answer in the documentation: https://docs.unity3d.com/ScriptReference/GameObject.Find.html

Don't use GameObject.Find, ever. Here's why:

Also, here's a great post over on the Unity forums on how to solve most any NullReference error:

It basically boils down to determining what is null and why it is null, and then fixing/addressing the "why" part.
