Assets/Save Game Script.cs(87,45): error CS1525: Unexpected symbol `(', expecting `)', `,', `;', `[', or `='

OH NO! It’s me again!
As the title said, Unity keeps giving me the error, but I can’t seem to spot it. Feel free to help.

You are trying to declare a number of methods inside of OnGUI(). I think if you put a ‘}’ on line 85 to close OnGUI(), it will address this specific problem. You will want to redo your indenting to place all these new methods at the same level as OnGUI().
