I am trying to use the Auto Fill feature, selecting a range of values and
dragging the + to fill in the range.

My problem is that when I select A, B, C, D, and drag the box down, instead
of getting A, B, C, D, E, F, G, H, etc., I get A, B, C, D, A, B, C, D, A, B,
C, D,

How do I get it to continue the series, rather than duplication the above?

The cells are formatted "general". (Windows XP SP2, Excel 2003)

Thank you,
