I think I'm losing my mind....

.......C...................D...........................E.........
1......1............10/25/2005...........10/26/2005
2......2............10/27/2005...........10/29/2005
3......0............10/29/2005...........10/29/2005
4......3............10/29/2005...........11/01/2005

This is how the data SHOULD look.

Column C is the duration of the project in days.  Column D is th
project start date.  Column E is the project end date.

In Column D I'm using the formula =IF(logical test,value if true,valu
if false).  As example, in D4 I'm using the formul
=IF(C3="0",E3+0,E3+1).  

In my limited understanding, this is supposed to mean that if C3 is
0, then D4 will report 10/29/2005, BUT if C3 is a number other than 0
then D4 will report 10/30/2005.

Here is the issue:  the formula =IF(C3="0",E3+0,E3+1) is ignoring th
E3+0 part - it ALWAYS adds 1 day to the duration,even when the C3=0.
Also, I tried flipping the true-false values by usin
=IF(C3="0",E3+1,E3+0).  In that case it ALWAYS adds 0 days to th
duration, even when the value is something other than 0.  

Any help would be GREATLY appreciated.  I know it must be m
misunderstanding how this formula is supposed to work.
