APEX

HI all Gurus

Using Apex 4.1.1 oracle 11g linux oc4j

I want to highlight a row where #column_value#='Y' to grey  keep others as normal report settings.

I have a simple sql query

SELECT PK_ID,
  FIRST_NAME,
  LAST_NAME,
  INITIAL_REG_DATE,
  MAIL_DATE,
  BEGIN_DATE,
  END_DATE,
  END_DATE-BEGIN_DATE as "#days",
  BEGIN_STATUS,
  END_STATUS,  
  COMMENTS,
  DELETE_FLAG,
 case when  DELETE_FLAG='Y' then 'GREY' else '#f0f0f0' end  DELETE_FLAG ,
INITIAL_REG_DATE+(END_DATE-BEGIN_DATE) "New Reg end date"
FROM SOR_TRACKING_DEL
where pk2_id =:P216_Detail
order by mail_Date desc

I created a Dynamic action

which will fir on on load , BIND on this classic report

$("input[name=f29]").each(function(){  
var lThis=$(this);  
if(lThis.is("Y")){  
  lThis.parents("tr:eq(0)").children("td").css({"background-color":"GREY"});  
} else {  
  lThis.parents("tr:eq(0)").children("td").css({"background-color":"#f0f0f0"});  
}  
});  

But this is not changing color as expected..

Kindly help me !

Thanks
