you have to enable the identity property for EmployeeID  after the first insert, the last inserted EmployeeID can be retrieved using SCOPE_IDENTITY()

DECLARE @LastEmpID int
INSERT INTO Employee
SELECT ....
SELECT @LastEmpID = scope_identity()
INSERT INTO Employee_Cell (EmployeeID, ... )
select @LastEmpID, ....

Use the @@IDENTITY system function.

Oops.. I guess SCOPE_IDENTITY would do a better job since it works within the same scope  :-)

so will this work?

INSERT INTO employee(john,doe)VALUES(first,last)
@lastID = scope_identity()
INSERT INTO employee_cell(@lastID,555-5555)

if there is an identity column on the Employee table thhis will work

INSERT INTO employee(first,last)VALUES('john','doe')
SELECT @lastID = scope_identity()
INSERT INTO employee_cell
SELECT @lastID,'555-5555'

this is what i have set for employeeid

Identity Specification    Yes
      (Is Identity)             Yes
      Identity Increment   1
      Identity Seed          1


are these settings correct to use scope_identity()?

Yes, it means it will start the seeding at 1 and increment by 1 for each row entered.
