I just did a reply, must be getting frustrated

Thank you, yes the calculation was on manual which I have changed. Also noticed that when setting the date format, the location was different each time I went in even though its set to English (US). So I have ensured that all are set and they are formatted to 14 Mar 01, but if I type say 28/4/14 it stays that way. Is there any other settings that could be causing my issue?
