\f0\fs24 \cf0 //** Tab Content script v2.0- \'a9 Dynamic Drive DHTML code library ({\field{\*\fldinst{HYPERLINK "http://www.dynamicdrive.com/"}}{\fldrslt \cf2 \ul \ulc2 http://www.dynamicdrive.com}})\
//** Updated Oct 7th, 07 to version 2.0. Contains numerous improvements:\
//   -Added Auto Mode: Script auto rotates the tabs based on an interval, until a tab is explicitly selected\
//   -Ability to expand/contract arbitrary DIVs on the page as the tabbed content is expanded/ contracted\
//   -Ability to dynamically select a tab either based on its position within its peers, or its ID attribute (give the target tab one 1st)\
//   -Ability to set where the CSS classname "selected" get assigned- either to the target tab's link ("A"), or its parent container\
//** Updated Feb 18th, 08 to version 2.1: Adds a "tabinstance.cycleit(dir)" method to cycle forward or backward between tabs dynamically\
//** Updated April 8th, 08 to version 2.2: Adds support for expanding a tab using a URL parameter (ie: {\field{\*\fldinst{HYPERLINK "http://mysite.com/tabcontent.htm?tabinterfaceid=0"}}{\fldrslt \cf2 \ul \ulc2 http://mysite.com/tabcontent.htm?tabinterfaceid=0}}) \
