Hi,

Column A has date, Column B has number of days required to finish the
task,
in Column C I want to use a formula which adds Column B( number of days)
to
column A but excludes holidays and weekends and adds only working days.

eg. Column A has 12/8/08 Column B has 7 days coulmn C should be 12/17/08 (
only working days to be added)

Thanks for your help.
