Change the formula in C1 to the following:

=IF(B1="","",A1+B1+1)

Then copy and paste down column C as far as you need it.

can anyone help me! i have created a gantt chart, but having the following
problem: column A contains qty of days, column B is start date, column C is
end date. i have set column C so that it adds column A + column B to give me
an end date, but if there is no start date, the end date displays 05/01/00.
A B C
E.g: 6 + (05/12/07) = 10/12/07 ( formula i am using or (C ) is =A+B+1)
6 + ( ) = 05/01/00 ( i want this to remain blank until i
put a start date
in as i have copied the formula down the cells of column C
any ideas???
thank you so much
although this solved the above problem, it has now caused another problem,
my fault i did not say what i was working on, i have created a gantt chart
in excel
and use the start and end dates to calculate work progress and for every day
counted in the end date, a designated cell will be highlited through out the
month.
the above formula you have sent has caused the whole of the month to be
highlited,
what i want is for the whole range of cells for that month to also remain
blank until the start date is entered.....
