days to dates

[rkaiser]

I need a little help. I want to create a spreadsheet that if given a start date will give you a forward date from a number, not counting weekends or holidays. This will be used to calculate lead times.

ex. Start date 9/5/2006 days till due 15, it would return a date of 9/26/2006.

Thanx for the help, in advance.
