Forms :: Changing Source Of Combobox

I have a form (named Example) to create reports by selecting fields from tables or queries. there is a option box (name is KynkSec) with two options (Table, Query) and a combobox named as KynkTurSec.I want to change the data source of combobox either table or query. By afterupdate, that combobox is requering the listbox "ListKynkAlan" and I can see fields of selected table or query. (That is my dream))Unfortunately I can not do that. Combobox is showing only tables or both of tables and queries. But not only query.

Here is str source of my combobox:

SELECT MsysObjects.Name, MsysObjects.Type FROM MsysObjects WHERE (((MsysObjects.Type)=1) AND ((Left$([Name],1))<>"~") AND ((Left$([Name],4))<>"Msys")) OR (((MsysObjects.Type)=5) AND ((Left$([Name],1))<>"~") AND ((Left$([Name],4))<>"Msys")) ORDER BY MsysObjects.Name; That is showing both of tables and queries.

And I wrote a code for KynkSec option box;

Private Sub KynkSec_AfterUpdate()
' Populate rowsource of KynkTurSec
Dim strSQL As String
On Error GoTo HandleErr
Select Case KynkTurSec

Case 1

strSQL = "SELECT MsysObjects.Name FROM MsysObjects" _
& WHERE(((Left$([Name], 1)) <> "~") And ((MsysObjects.Type) = 1) And ((Left$([Name], 4)) <> "Msys"))
Order BY(MsysObjects.Name)

Case 2

strSQL = "SELECT MsysObjects.Name FROM MsysObjects" _
& WHERE(((Left$([Name], 1)) <> "~") And ((MsysObjects.Type) = 5) And ((Left$([Name], 4)) <> "Msys"))
Order BY(MsysObjects.Name)
Case Else
End Select

[code]...

But this code is not working and giving a warning messsage "Sub or function is not defined"..So How can I change the source of combobox, either table or Query?
