Welcome to the forum @developedbymayur

In order to make code readable and usable it is necessary to surround your code with three backticks (also known as a left quote or backquote `````)

````auto
``` 
   code goes here 
```

````

You can edit and correct your post by clicking the pencil ✏ icon.

See this post for more details - [How to share code or flow json](https://discourse.nodered.org/t/how-to-share-code-or-flow-json/506)

To debug your code you can add node.warn() statements to show intermediate results in the debug pane. For example, after the `total += ` line you could add

```auto
node.warn(`total = ${total}`)

```

By using that technique you can follow the flow through and see where it is failing.
