Multer file upload error Error: Unexpected field

I am trying to upload file on NodeJS using multer but it gives error of Error: Unexpected field.

I am following this tutorial http://code.runnable.com/VNX-T8fdt5Y4X-mv/fileupload-for-node-js-and-hello-world.

Here is my code:

var express=require("express");
var multer  = require('multer');
var app=express();
var done=false;

/*Configure the multer.*/

//app.use();

/*Handling routes.*/

app.get('/',function(req,res){
    res.sendfile("./index.html");
});

app.post('/',multer({ dest: './uploads/'}).single('upl'),function(req,res){
    if(done==true){
        console.log(req.files);
        res.status(204).end();
    }
});

/*Run the server.*/
app.listen(3000,function(){
    console.log("Working on port 3000");
});

On the HTML

Error I am facing is

HTML filename and myimage should be same as .single('upl')

So code is

var express=require("express");
var multer  = require('multer');
var app=express();
var done=false;

/*Configure the multer.*/

//app.use();

/*Handling routes.*/

app.get('/',function(req,res){
    res.sendfile("./index.html");
});

app.post('/',multer({ dest: './uploads/'}).single('myimage'),function(req,res){
    if(done==true){
        console.log(req.files);
        res.status(204).end();
    }
});

/*Run the server.*/
app.listen(3000,function(){
    console.log("Working on port 3000");
});
