Hello in Excel 2003
This is my formula =IF(M18=" "," ", M18+60)

In Cell M18 person will enter a date
Cell M 19 is formated as date formula is ( if cell M18 is blank then
blank, otherwise the date on cell M18 plus 60 days )
The problem is if I add any date to cell M18 I get the correct answer , but
if cell M18 is blank I get a date February 29 1900
How Do I formula so that if M18 is blank them M19 is blank
