How can I count results or expression

[#1]

I have an expression like that

if(count(
{<
[Year of conclusion]=     {2014},             
[Contract Conclusion Date] -= {"<=$(=Date(vNewC))"}

>}
DISTINCT([Contract Number])
),'New','Old')

How can i count only new contractc and old ones

somefing like

count([My ecpression] = 'New') does not work

or

count({<[My ecpression]={'New'}>} [My ecpression] )
