Help with a calculated field in a PivotTable

Hi, I am trying to write a formula for a calculated field inside a Pivot Table.   I want to return the value 1 if the row value is equal to "New York", and zero otherwise.  My formula is

 =IF(ISNUMBER(FIND(City, "New York" ) ),1,0 ) 

However, the formula always returns zero.   Please see the attached screen shot.

Thanks, Ben.
