Queries are not seeing NULL Values in my DB

For some reason my Stored Procs are not recognizing NULL values within my database:
For example:
Select *
From Results
Where
(
home_Phone IS NULL
)
All the home_Phone vaules that are NULL are not being picked up by the query.
Any ideas are appriciated.
Thanks in advance everyone.

Perhaps rather than NULL, the home_Phone is blank (a different thing). That is, rather than NULL, the field is an empty string.|||

Are you sure the values are NULL and not a blank?

Try where home_phone = '' to be sure.

I am confused. How is that query using an aggregate function?
