This message occurs when displaying the page of "jqui_test".
Browser displaying this error: IE 8, 32 bit and SRWare Iron (same as Google Chrome)
Please note - I am new to drupal.
I have installed the module by following the instructions in // $Id: README.txt,v 1.5.2.2 2009/06/21 03:43:03 sun Exp $, and section -- JQUERY UI 1.7 --

ADDITIONAL: I found a typewriting error in "jqui_test.module" there is a call to "ui.selecttable.js", but the module meant is "ui.selectable.js". I have corrected it locally.

If you need more info, please let me know.
VERY GOOD NEW YEAR
