combo box error

I have a combo box that displays a list of records.
When a user clicks on a combo box selection all the textboxes will populate with a value from the selected record of the combo box. But instead of populating the fields it gave me an error message: Object doesnt support this property or method

I am developing in Access 2000 and using SQL Server as back-end.

Sub Combo5_AfterUpdate()
' Error occurred next line
Me.RecordsetClone.FindFirst "[ID] = " & Me![Combo5]
Me.Bookmark = Me.RecordsetClone.Bookmark
End Sub

Thank you!This ain't be SQL problem could be Access, check with Access forums.
