I am using the VLOOKUP formula with HSSFWrokbook and the generated Excel file shows #VALUE! error. it says that "a value used in the formula is of the wrong data type". I dont understand it.
which turns to
Where $F8 column is a date value = 6/30/2011 11:25:39 AM, and it is dispalys like "6/30/2011" in F8.
It works with the String value, like if i directly provide the value e.g. summaryCell.setCellFormula("VLOOKUP(\"TOTAL\",A8:D30,4,FALSE)");
Its works fine. But it doesn't work with the reference like $F8.
