Any chance your pivottable range needs to be readjusted.

You can rightclick on the pivottable and choose Wizard and step backward to get
to the step that asks what range to use (if you want to do it manually).

Or maybe you could use a name that will react to row insertion/deletion.

Debra Dalgleish has some notes for dynamic range names:
