I am trying to copy a 3-d reference from a cell to others below it using the
fill handle. According to the book I'm referencing, the formula should copy
and adjust automatically. But when I drag the fill handle, the formula is
not adjust.

Example:
Cell A1: ='Section 1'!B22
If I click the fill handle from A1 to C1 I would expect the values:
Cell b1: ='Section 2'!B22
Cell c1: ='Section 3'!B22

Thanks,
Gall
