Hi guys,

Thanks for helping me out on this!
I did mark the whole document. It works when I make a new worksheet, but for some reason I am not able to use it in my excisting document, it will only mark the first row.
If I copy a section with dates from my old document to the new worksheet, it will work, but not if I try to copy the whole column...strange. Something in my old document is blocking this function.
