Excel 2007 - Group and Outline Problem

[MsMarieH]

I have a document with group and outline applied in Excel 2007. The plus symbols show along the lefthand side. However, the 1-2-3 do not show on the left so you can see all Level 2s, for instance. I checked the Advanced Option and verified that the check box is checked to Show outline symbols if an outline is applied.

Any other ideas as to how I can get that 1-2-3 to show?

Thanks for your help!
