I keep track of my job hours in excel. At the end of every month I delete my
data and save it with the next months name so the new month is empty but the
present month is still saved with all the info. Last week somehow I messed up
and deleted the data in the present month. I need to know if there is a way
to erase this mistake even tho it hapened last week, the last time I used the
spreadsheet.
