Order report excel plug in error

Hello,

I am trying to use the excel plug in to extract a IFS report that normally is created as .pdf.  

I uploaded a new .rpl file to the cust_age_analysis_rep report file layout.  When I try to run the report, I get the following error:

My .rpl file looks like this:

<?xml version="1.0" encoding="UTF-8"?>
<report-layout>
    <properties>

        <variables>
            <!-- not used by this plugin -->
        </variables>
    </plugin>
</report-layout>

Do you know what might be wrong with the format of the .xml?

Thanks,
