The below piece of code carries out a vlookup on a defined cells value and produces a result in sheet one, however if the column index number in sheet 2 (Database) is empty the result 00/01/1900 is produced.

I'm not sure how to say leave the result blank if the column index number is blank, can anyone help out with this additional bit of code please?

Excel 2010
Userform = Tab 1
Database = Tab 2

            With Sheets("Userform").Range("G21:J21")
                .Value = "Appeal date:"
                Sheets("Userform").Range("M21:O21").Select
                Selection.NumberFormat = "dd/mm/yyyy;@"
                ActiveCell.FormulaR1C1 = "=VLOOKUP(R[-18]C[4],Database!R[-18]C[-11]:R[-1]C[38],9,FALSE)"
            End With
