        This tests that the multi-file upload control works correctly.  This test and the resources/multiFileResources must be placed on a web server so the test can be run manually.<br>
        Choose "testFile1.html" "testFile2.html" and "testFile3.html" and submit the form. <br>
        You should see a "Test Passed" or a "Test Failed" message after submitting the form.<br>
