Crystal Reports Issue with Data Selection Filter:

Message

     I am getting issue while using the Data Selection Filter: in a report while doing the settings:-

When i am using 
{GetOverrideRequest.area} in %d 
While running the report it is pulling no data

When using given below selection criteria it is pulling all the data even after giving the area value.

{GetOverrideRequest.area} = %o

Please help to modify this criteria so that it will pull only that data for which we will provide area value.
