I have a text box that represents Hours worked, I also have a text box that
represents Adjusted Hours worked.  If user wants to override the Hours worked
they enter a value in the Adjusted Hours worked text box.  In doing so the
Adjusted hours worked field in the database would then be updated to the
value entered, but in the event the user doesn't enter an adjusted hours
figure the database field should contain Null.  How do I pass the value null
from the adjusted hours worked text box, since it would be blank(empty, =
nothing, or whatever) to the database field?

Any help would be greatly appreciated, thanks in advance.
