Hi,
Highlight the whole sheet and press Merge, then sort it. You are sorting by
rows however one of them is using two columns that is the reason why you get
that message,
if this helps please click yes, thanks

lI'm using Microsoft XP. In Excel, I'm trying to sort, but I get a message
box that says."This operation requires the merged cells to be identically
sized." I have merged cells within the rows, but not in the columns (and I'm
sorting by rows).
