Hi,
By "not an option" you mean Freeze Panes is grayed out?
First, when you want to freeze panes, it is not necessary to split screen
first, in fact that step is a waste of time, go directly to freeze panes.
Second, yes you can not have both freeze panes and split screen active at
the same time, but Freeze Panes is still active (an option) when split screen
is on.
Third, if freeze panes is not available check to make sure
1. If the worksheet is Protected.
2. If the workbook protection is on.
3. If you are in Edit mode.
If these help, please click the Yes button
