Calculated filed total pivot form

[Boss]

Hi,

I have a master table with employee information with emp ID as primary Key.
Other informations are name, tenure in organisation, designation etc.

I have prepared a Pivot form using the Wizard. I was trying to get the count
of employee with more that 6 months as tenure in the organisation using
Calculated field option in the menu.

Please help me with the corrrect syntax.

Thanks!
Boss
