Web controls and design features eliminated. Office 2007 will ship
without the Office Web Components, ActiveX controls that support data
access, spreadsheets, charting, and PivotTable analysis in Internet
Explorer. This means existing Web pages that use the controls will not
work on Office 2007 systems, unless users or administrators separately
download and install the controls (which will still be available from
Microsoft). Web page design features that require the controls have
been removed from Office 2007; these include Excel's Save As Web Page
"Add interactivity" option, and the Access Data Access Pages design
feature. (See "Office 2007 Retires Web Controls".)

Excel 2007 does not have Excel's Save As WebPage "Add interactivity" option.
Is there another way to do this in this version?

Thanks
