Well, you'll have to stop using ID's, use classes instead. It's easier if you start using a framework, such as jQuery.

From what I understand after reading the post, you are wanting to add new div's into the container div each time a visitor clicks for a new calculation.

function add()
{

       var j=1;
       var v1 =document.getElementById('ttlBoxes').value;
       var v2 =document.getElementById('boxno').value;

       var d1=parseInt(document.getElementById('ttlBoxes').value);
       var d2=parseInt(document.getElementById('boxno').value);
       if(v1!=""&& v2!="")
      {
       if(d2<d1)
      {
       //This div does not exist yet, you have to create it
	   var divTag = document.createElement("div");
            divTag.setAttribute('class','dynamicDiv'); 
	   var mainDiv = document.getElementById("my_div");
	   //setting the class attribute - each id HAS to be unique
       
	   //creating the table that will populate the new div, since the div does not exist - neither does the table. 
	   var calcTable ='<table width="101%" border="0" align="center" cellpadding="5" cellspacing="1" class="entryTable">';
	   calcTable += '<tr ><td  width="150" class="label" ><select id="boxtype" name="boxtype+j" ><option value="select">Select</option><option value="Amb">Amb</option><option value="Frz">Frz</option><option value="Ref">Ref</option><option value="Gen">Gen</option></select>&nbsp;&nbsp;&nbsp;&nbsp;';
	   calcTable += '<select id="box" name="box"><option value="select" >Select</option><option value="OurBox">Our Box</option><option value="DrBox">Dr.Box</option><option value="Other">Other</option></select>GrossWeight<input type="text" name="grWeight"  id="grWeight" value="0" onclick="calc(this)" readonly="readonly" /></td>';
	   calcTable += '<td width="150" class="label" ><p>Box Nos.<input name="boxno" type="text" class="box" id="boxno" size="20" maxlength="255" value=""  /></p>';
	   calcTable += '<p>ChargebleWeight<input type="text" name="crWeight"  id="crWeight" value="" /></p></td>';
	   calcTable += '<td class="label" ><p>Dimension<input name="l" type="text" class="box" id="l" size="3" maxlength="255" value="" />x<input name="b+j" type="text" class="box" id="b" size="3" maxlength="255" value=""  />x';
	   calcTable += '<input name="h" type="text" class="box" id="h" size="3" maxlength="255" value="" /></p></td></tr></table>';
       //add the table to the new div
		divTag.appendChild(calcTable);
		//add the new div to the container div
		mainDiv.appendChild(divTag);
}
else if (d2==d1)
{
alert("Box No. has reached max limit");
}
else if(d2>d1)
{
alert("OOps more than total numbers ");
}
}
else
{
alert("Please enter total Box/Box nos .");
}
}

function calc(){ 
if ( isNaN(document.getElementById("l").value) == true )
{
alert('The  value is not numeric');
document.getElementById("l").value.focus();
document.getElementById("l").value.select();
return false;
}
if ( isNaN(document.getElementById("b").value) == true )
{
alert('The  value is not numeric');
document.getElementById("b").value.focus();
document.getElementById("b").value.select();
return false;
} 
if ( isNaN(document.getElementById("h").value) == true )
{
alert('The  value is not numeric');
document.getElementById("h").value.focus();
document.getElementById("h").value.select();
return false;
}
if ( isNaN(document.getElementById("boxno").value) == true )
{
alert('The  value is not numeric');
document.getElementById("boxno").value.focus();
document.getElementById("boxno").value.select();
return false;
}

   var l1 =parseFloat(document.getElementById("l").value);
  var b1 =parseFloat(document.getElementById("b").value);
  var h1 =parseFloat(document.getElementById("h").value);
  var box = parseFloat(document.getElementById("boxno").value);
 
     var r =(l1*b1*h1/6000)*box; 
     ( document.getElementById("grWeight").value) = r; 
     
}

I also combined all of the code, you don't need to specify it with each function. It's just a bit easier to read.

I admit to not testing it, I did not have the time but hopefully it works or at least helps with some code syntax.
