MVC 3, url parameter does not separate

I'm getting familiar with MVC 3. I got stuck on the first thing in the tutorial - unbelievable!

This is my Controller-method:

    public string Welcome(string name, int numTimes = 1)
    {
        return HttpUtility.HtmlEncode("Hello " + name + ", NumTimes is: " + numTimes);
    }

And the url I'm using:

http://localhost:49770/HelloWorld/Welcome?name=Adam?numTimes=4

Which should produce this:

Hello Adam, NumTimes is: 4

But it actually becomes this:

Hello Adam?numTimes=4, NumTimes is: 1

It does not separate the params! It must be something really simple I've missed!

When forming strings to send parameters, especially if you use JSON to do that with AJAX, in between each field sent must be an &. The & acts similar to a comma in method parameters. Whereas a call from code may be Welcome("Adam",4), from a url it would look like /Welcome?name=Adam&numTimes=4. The ? tells MVC (assuming regular routing) to use the action found, in this case Welcome. Following that are name value pairs, separated by the & symbol.

Use http://localhost:49770/HelloWorld/Welcome?name=Adam&numTimes=4

The series of key/value pairs in a query string are separated with an ampersand.

See http://en.wikipedia.org/wiki/Query_string for details.

You've got 2 question marks (?). change the second one to an ampersand (&)

http://localhost:49770/HelloWorld/Welcome?name=Adam&numTimes=4
