Excel-2010 : Have a spreadsheet that contained 4940 lines and 3 columns already sorted. Added 79 lines and requested a sort A - Z, expand the selection, for column C. When finished the only sort that took place was in the 79 lines that I added, instead the mergin them with the other 4940, despite the fact that I highlighted all 5024 elements. What am I doing wrong? Is there a solution? Thank you
