How To Return Multiple Table Values From A Function

Hi,
We Have Been Trying To Convert Some Pf The Procs Into Functions Of Late,but There Is A Problem :-we Have Been Unable To Return More Than 1 Table Value From A Function.

Create Function F_clusters()
Returns @ki Table(names Nvarchar(200),total Int),
As
Begin
Insert @ki
Select Names,count(distinct Chremail) As From Customer
Where Chremail Is Not Null
Return
End

This Works Fine :-
And Gives The Reqd. Results.

But,

If I Am Using The Same Function To Return Two Tables Then It Doesn't Work,could You Pls Chk.



Create Function F_clusters()
Returns @ki Table(names Nvarchar(200),total Int),@k2 Table(names Nvarchar(200),total Int)
As
Begin
Declare @cnt Int
Set @cnt = 1
While @cnt <= 2
If @cnt =1
Begin
Insert @ki
Select Names,count(distinct Chremail) As From Customer
Where Chremail Is Not Null
Set @cnt = @cnt + 1
End
If @cnt =2
Begin
Insert @k2
Select @naamre,count(distinct(a.intcustomerid)) As Pura_ginti From Trcustomerpreference03july A Inner Join Cleancustomer B
On A.intcustomerid = B.intcustomerid
Where Chremail <> ' ' And Chremail Is Not Null
And Intpreferenceid In (6,7,2,3,12,10)
Set @cnt2 = @cnt2 + 1
End
End
Return
End


Can We Return Two Tables Or Is It Not Possible ?
Pls Chk Into This And Tell Me.

Thanks.
