I am getting an error:
Exception from HRESULT: 0x800A03EC
whenever I set the formula for the range as:

```
        Range range = destinationSheet.Range["A1"];
        string[,] formulaString = new string[numberOfRows, 1];
        range = range.Resize[numberOfRows, 1];

        for (int count = 1; count <= numberOfRows; count++)
        {
            string worksheet = "Sheet1";
            string cellRef = "A1"
            string formula = string.Format("={0}!{1}", sourceSheetName, cellRef);
            formulaString[count-1, 0] = formula;                
        }

        range.set_Value(Type.Missing, formulaString); 
        range.Formula = range.Value;   // getting exception here

```

what might be the reason for this
