Adding months to start date to get end date

I have found several suggestions how to solve a similar problem, but none of them seems to work for me... I know it is no challenge for all you sharp minds, so please help me with the following:

In G6 I have a start date (01-02-2011)
In F6 I have a number of months (24)
In H6 I need a formula to calculate the end date...

Below is one of the suggestions I found in here - but I cannot get it to work... :-(

=MIN(date(year(G6);month(G6)+F6+{0,1};DAY(G6)*{1}))

I use Office 2010...

Look forward to your help... :-)
