number of days between dates excluding weekends

Hi All

I need some urgent help. I am trying to design a spreadsheet that work with approval dates.

Basically it has to work as follows:

I have a column containing the date paper work is completed.
I have a column containing the date the deal is approved.

I would like in the third column to show the amount of dyas it took to get the approval e.g date received less date approved.

Now the number of days has to exclude weekend days.

Please help

Thanks

Thanks guys. thats exactly what i wanted.

thanks a million
