Building Widgets code challenge error message tells me to extract args. I have. Help me find my mistake?

Hi --

I'm doing the first Code Challenge for Building Wordpress Widgets, Stage 4. The fourth task is:

Inside of the widget function, below the extract function, apply the widget_title filter to get the title of the instance. Assign it to a variable named title.

I've taken the code from the Treehouse project files:

    function widget( $args, $instance ) {
    // Widget output

    extract( $args );
    $title = apply_filters( 'widget_title' , $instance['title'] );

}

I get an error message which says:

Bummer! The first thing inside the widget method, use the extract function to make $args into local variables.

I've done that, using the Treehouse code exactly. I searched around to try to find another way to write it, but this seems to be the standard way.

Could you guys help me figure out what I'm doing wrong?

Thanks!
