Inject Factory into Factory

How do you make a factory available from another factory? Using the below the console tells me there is an error (injector:unpr).

angular.module( 'fb.services', [] ).factory( 'getQueryString', function() {
    return { call: function( qs ) {
        var result = {}, queryString = qs.substring( 1 ), re = /([^&=]+)=([^&]*)/g, m;
        while ( m = re.exec( queryString ) )
            result[decodeURIComponent( m[1] )] = decodeURIComponent( m[2] );
        return result;
    }}
});

angular.module( 'fb.services', ['fb.services'] ).factory( 'getReferrer', function( getQueryString ) {
        var qry = getQueryString.call( 'query=string&this=that' );
        // fails to find getQueryString
});

You just need to do:

angular.module( 'fb.services').factory( 'getReferrer',['getQueryString', function( getQueryString ) {
        var qry = getQueryString.call( 'query=string&this=that' );
        // fails to find getQueryString
}]);

When you use the second argument in the module declaration angular.module( 'fb.services','fb.services'] ) it means you are redefining/defining the module again with new dependencies, which means anything registered previously are lost.

After you have defined your module, you just access it by doing angular.module( 'fb.services') (omit second argument, so it becomes a getter of the module that has been already defined)
