Select "Contact Us" from the top-level menu, enter a couple of characters in just one of the fields and press "Submit". This will cause the page error.htm to be displayed. Now mouseover "Photos" on the top-level menu which should at this point display a submenu. Dependent on the browser, an error will occur as follows:-
Internet Explorer 6 will fail to display the submenu and instead display a Javascript runtime error. Checking out the debugger this turns out to be line 22 of the function openSubmenu() in mm_navframes.js which reads: var mNum=mm_tf.getMenuByName(_mi[mm_si][3])
Firefox just fails to display the submenu!

Opera fails to display the submenu and on mouseover displays "address: javascript: void(0)" rather than an address.
I would assume that the error is due to the fact that the browser cannot find either milonic_src.js and/or menu_data_body.js or one of the other two javascript files as referenced from error.htm, possibly because the script calling the page is running from a cgi-bin directory rather than the normal HTML directory. However, prefixing the location of all of these javascript files with the absolute path of "http://www.sorrentobarcrete.com/" makes no difference. Has anyone any thoughts on how to get around this problem please?
