PivotTable not displaying properly as webpage

I'm saving a PivotTable to be viewed on our Intranet site. Yesterday
it was working fine with the drop-downs to select a date to view,
etc.

I re-saved it today and now it displays as more of a spreadsheet
rather than a pivot table. The drop-downs are gone, so you can no
longer select a date.

When I saved it as a webpage, I selected "Add Interactivity" and
Republish Sheet and clicked the "Publish" button. It gave me the
option of spreadsheet or pivot table functionality. I chose pivot
table functionality.

I really need the pivottable functionality of this.

Thanks.
