[Plugin: Our Progress] Widget not appearing.

I am attempting to use the fundraising thermometer at my wordpress blog. because I want it to be on permanent display and not lost in an old post, I want to use it as a widget int he sidebar. This is what the instructions say:

= How do I display the results? =

If you would like to display the current money raised, include the following code in your WordPress theme: <?php echo show_ourprogress() ;?>

To display the graphic results, include the following code in your theme: <?php echo show_ourprogress_graphic();?>

= Can I include it in a Widget? =

Yes! If you add a text widget to your sidebar, simply paste the above code into the text area and the plugin will work as a widget.

Well, I have uploaded and activated the plugin, and pasted this into a text widget: <?php echo show_ourprogress() ;?>

Nothing. No graphic appears. I wish I could attach a jpeg to show you that I really am placing this code into the text widget. In that same text widget is the code to make other buttons appear, and they are appearing fine, but this one is not.
