Row 15 Col 15 - Value '24-Jan-12' is not a supported date format
Row 15 Col 16 - Value '24/1/2013' is not a supported date format
Row 18 Col 15 - Value '01-Feb-12' is not a supported date format
Row 26 Col 15 - Value '01-Feb-12' is not a supported date format Is there something I am missing? I have a lot of data and I don't to want add each date manually.... Cheers Mick
