Trouble making money system

Question

I am coding a money system in JavaScript, and am making a function that adds money to the total amount. But I get two errors:

Assets/Money.js(5,9): BCE0044: expecting }, found 'public'.
Assets/Money.js(11,1): BCE0044: expecting EOF, found '}'.

Here is my code:

 #pragma strict
 
 function AddMoney(MoneyToAdd)
 {
     public var Money : GameObject;
     public var MoneyAmount : float;
     public var NewMoneyAmount : float;
     
     NewMoneyAmount = MoneyAmount + MoneyToAdd;
     Money.guiText.text = NewMoneyAmount;
 }

Edit: Ok, I changed it a bit, but now get the error: Assets/Money.js(17,19): BCE0043: Unexpected token: 5.0.

Here is the new code: #pragma strict

 class ChangeMoney{
     public var Money : GameObject;
     public var MoneyAmount : float;
     public var NewMoneyAmount : float;
 
 function AddMoney(MoneyToAdd : float)
 {
 
     
     NewMoneyAmount = MoneyAmount + MoneyToAdd;
     Money.guiText.text = "£" && NewMoneyAmount;
     }
 }
 
 function AddMoney(5.0)

Please could I have an answer for both bits of code.

In you first piece of code, you are trying to define if you local variables should be either public or private, but inside a body, ie "{ ... }" the functions are local to that body, you might say private. All variables created inside a body, also 'die' when reaching the end of a body, ie a "}".

The keywords public and private only makes sense when defining class variables, as they determine whether other instances can access these variables directly.

The other piece of code:

You cannot define a function like this:

 function AddMoney(5.0)

When defining a parameter, you must define its type and some name, that you define, some language allow you to also define a default value for a parameter, but not in unity-javascript, therefore you must do it like you do previously:

 function AddMoney(value : float)

If you want to let AddMoney take a default value of 5.0f, then you cannot do this in unity-javascript, however you can do this in unity-c#, although it cannot be called from a javascript file, and therefore to utilize this functionality, you must write your whole project in c#, or create some extra wrapper functions in c# which can be called from javascript, nonetheless; messy.

I am sorry, but I still do not understand the second one. What do I write for the function?

Let me start by asking; what is it you want to achieve with that line/function? You have already defined the function AddMoney above.
