Can't set financial year end

Can't set financial year end

Hi,

I've prepared my accounts for the financial year January - December 2011. There's a little problem when it comes to the figures displayed on my Balance Sheet on 31 December 2011, whereby the P&L is taken for the period of June - December 2011 instead of from January 2011.

Is this a problem with setting up the proper start to the financial calendar (January as opposed to June)? If so, how do I change the start of the financial year? Can't seem to find it. 

Thanks in advance for the help!

Regards,
Suren
