Greetings,
I need help figuring out how to leaved blank cells for missing dates in a series of sequential dates. For example, If my series is (in (m/d/y) format):

1/10/1999
1/12/1999
1/13/1999
1/14/1999
1/17/1999
1/18/1999

But I want it to be:

1/10/1999
(blank cell)
1/12/1999
1/13/1999
1/14/1999
(blank cell)
(blank cell)
1/17/1999
1/18/1999

How do I do this?

Thanks
