I have this javascript

function deleteRow(tableID) 
      {
            try {
            var table = document.getElementById(collct_table_body);
            var rowCount = table.rows.length;

            for(var i=0; i<rowCount; i++) {
                var row = table.rows[i];
                var chkbox = row.cells[0].childNodes[0];
                if(null != chkbox&& true == chkbox.checked) {
                    if(rowCount <= 1) {
                        alert("Cannot delete all the rows.");
                        break;
                    }
                    table.deleteRow(i);
                    rowCount--;
                    i--;
                }


            }
            }catch(e) {
                alert(e);
            }

But when I try to delete a row using this it shows an error "cannot read property 'rows' of null type error"

Is there any error in this javascript Im using?Can some one help me out?

You're missing the quotes

document.getElementById("collct_table_body");

or, may be this is a variable (which I don't see in your code, global var?? we will never know)

var collct_table_body = "someID";
