Your code crashes when you remove an input box in an 
unnordened way, try this to check it out, first add the 
1st, then the 2nd and finally the 3rd input box, then 
remove the 3rd, then the 2nd and finally the 1st input 
box, if you do this your code works correctly, but if you 
remove any input box with no order, let say remove the 
1st, then it crashes.

I made a little change to the removeRow function that 
allows it to delete textfields out of sequence. Please let 
me know if you implement this! - Justin

function removeRow(tbl,num)
    var table = document.getElementById(tbl);//adentification of table
    try {

      if(num >= row_no){
      table.deleteRow(row_no);//deletion of the clicked row
        table.deleteRow(num);//deletion of the clicked row

    } catch (ex) {
    if(row_no<=3)//if row is less than 3 then the button will again appear to add row

Oops. I changed the element name at the bottom of my
 example from "add" to "Button". Watch out for that! Using 
the original example code above, it should still 
be "add". -Justin

Code works great but how would you go about adding a unique value to each new textfield?
