Hi
i need help in a issue where i am not able to fetch records based on a date parameter passed to a soql query in a controller class for a VF page.
The issue is with the line 10 in the VF page code where it takes date as an input, and passes it to the controller class and used in the soql in line 14, which return no records even though its there. If i hardcode any date in the soql query as in line 15 then records are returned. 
can anybody help me to correct this as i am not getting any error in the code written but it does not seems to work.
