Find date using start date and number of network days

Hello,
I have the following problem

In A1 i have the today date
In colum B i have some values e.g B1=2, B2=5, B3=3, .....
I want in column C to find the date using A1 as start date and adding values of column B as networkdays

E.g C1= 9/7/12 (today+2 networks days)
C2 = 12/7/12 (today + 5)


Is it possible?

Thank you in advance
