Took me hours to find out why a simple formula as this one did always end up in a Correlation Error !
And answers is simple, when logging on to a Remote Deskop using a different regional settings, you need to use
An other example that might be usefull to know
=TEXT(From;”yyyy”) results in 2013
=TEXT(YEAR([Start Date])) results in 2.013
ALMOST ANY FORMULA YOU CAN PUT TOGETHER IN EXCEL, YOU CAN COPY TO A SHAREPOINT CALCULATED COLUMN AND IT SHOULD WORK JUST FINE.
