I was wondering if anyone has had dealings with hiding rows? My conundrum is, I have a spreadsheet with 800 rows of data, each row consists of 18 columns and when any cell in this array is selected, I would like to automatically hide all of the rows above the selected row and below it. The other trick is, that when I exit the sheet (move to another worksheet in the same workbook), all of the rows automatically unhide. Any ideas?
