Need Help with Fixing Errors

Hey all, I am a beginner in coding. I encountered a few errors that I can't seem to fix.



Line 28 and Line 33 says, "Feature 'local functions' is not available in C# 4. Please use language version 7.0 or greater."
I tried fixing this by installing Microsoft.Net.Compilers as shown when I look the error up, but I still have these problems.
Line 24 says I need a definition when I thought I added one?
Line 25 says cannot convert object to int. I have no clue on that one.

 

Put your code in code tags in forum, don't send file. https://forum.unity.com/threads/using-code-tags-properly.143875/

You have big problems with brackets, here you are short tutorial:

Example of correct code structure

Code (CSharp):

1. public class NameOfClass
2. { // starts class's block
3.  
4.     void Method() // declare method
5.     { // starts Method's block
6.           foreach(var item in collection)
7.           { // starts foreach loop block
8.                // code
9.           } // ends foreach loop block
10.     } // ends Method's block
11.  
12.    void SecondMethod() // declare second method
13.    { // starts SecondMethod's block
14.        //code
15.    } // ends SecondMethod's block
16.  
17. } // ends class's block

You can't do something like this.

Code (CSharp):

1. public class NameOfClass
2. { // starts class's block
3.  
4.     void Method() // declare method
5.     { // starts Method's block
6.         void SecondMethod() // declare method in method
7.         { // starts SecondMethod's block
8.              foreach(var item in collection) { } // inlined start and end foreach loop
9.              item.ToString() // you are outside loop
10.         } // ends SecondMethod's block
11.     } // ends Method's block
12.  
13. } // ends class's block
