    Your date format is wrong. In general, you could benefit from this function:

    ' Converts a value of any type to its string representation.
    ' The function can be concatenated into an SQL expression as is
    ' without any delimiters or leading/trailing white-space.
    '
    ' Examples:
    '   SQL = "Select * From TableTest Where [Amount]>" & CSql(12.5) & "And [DueDate]<" & CSql(Date) & ""
    '   SQL -> Select * From TableTest Where [Amount]> 12.5 And [DueDate]< #2016/01/30 00:00:00#
    '
    '   SQL = "Insert Into TableTest ( [Street] ) Values (" & CSql(" ") & ")"
    '   SQL -> Insert Into TableTest ( [Street] ) Values ( Null )
    '
    ' Trims text variables for leading/trailing Space and secures single quotes.
    ' Replaces zero length strings with Null.
    ' Formats date/time variables as safe string expressions.
    ' Uses Str to format decimal values to string expressions.
    ' Returns Null for values that cannot be expressed with a string expression.
