the odd thing not impede functionality. also, error message, although showing on browsers, prominent on ie8, displays "error on page" message @ bottom left hand corner of page.

i've tried different things, such js file order, performing try/catch statement (which doesn't work on either), , have googled extensively without results. tried suppressing errors, works, that's not optimal.

i'd appreciate assistance. thanks!

you calling functions doesn't seem exist in line (and in other lines well): must either declare functions or remove eventhandlers calls undefined functions.

var tablerow = '<td id="' + titletabid + '" onkeyup="menu_key(event)" onmouseout="menu_unhover(this)" onmouseover="menu_hoverroot(this)" class="tab-outer-container"><table width="100%" cellspacing="0" cellpadding="0" border="0" style="" class="ms-topnav zz1_topnavigationmenu_4"><tbody><tr id="mouse"><td style="white-space: nowrap;"><a ' + urltabshow + ' style="" class="zz1_topnavigationmenu_1 ms-topnav zz1_topnavigationmenu_3">' + titletabname + '</a><td valign="top" style="width:0pt;" ><img style="border-style:none; vertical-align:top;" alt="" src="http://mysite//globalnavscripts/dropdown.png"></td></tr></tbody></table><div style="position:absolute;height: 0px;z-index:1;"><div id="' + showtabpd + '" class="zz1_topnavigationmenu_8" style=""><table cellspacing="0" cellpadding="0" border="0" style="top: 0px;" id="' + showtabappend + '"></table></div></div></td>';
