Running a query this error appears "undefined function 'left" in expression error. The query has not been revised. Any ideas ?? Thanks
Open any module in Design view.
On the Tools menu, click References.
Click to clear the check box for the type library or object library
marked as "Missing:."
An alternative to removing the reference is to restore the referenced
file to the path specified in the References dialog box. If the
referenced file is in a new location, clear the "Missing:" reference
and create a new reference to the file in its new folder.
