for($a=1;$a<=(int)($_POST["hdnMaxIN"]);$a++)
       {
			   if(move_uploaded_file($_FILES["fileIN_"][$a]["tmp_name"],"myfile/".$_FILES["fileIN_"][$a]["name"]))
			   {
				   $sqlIN = "INSERT INTO file_inv (invoice_no,inv_file,id_job) VALUES ('".$_POST["invoice_".$a]."' , '".$_FILES["fileIN_"][$a]["name"]."' , '$max_id')";
			   }

	//*** Column 1 ***//
		newCell = newRow.insertCell(0);
		newCell.id = newCell.uniqueID;
		newCell.setAttribute("className", "css-name");
		newCell.innerHTML = "<center><INPUT TYPE=\"TEXT\" SIZE=\"10\" NAME=\"invoice_"+intLine+"\"  ID=\"invoice_"+intLine+"\" ></center>";

		//*** Column 2 ***//
		newCell = newRow.insertCell(1);

		newCell.setAttribute("className", "css-name");
		newCell.innerHTML = "<center><INPUT TYPE=\"FILE\" SIZE=\"10\" NAME=\"fileIN_"+intLine+"\" ID=\"fileIN_"+intLine+"\" ></center>";
		document.checkform.hdnMaxIN.value = intLine;
