so

Answer 1

I ran into a similar problem, and I know that is not an answer to the question, but it can be of help to someone with this kind of problem:
if there is need to put the elements of two or more forms in a given sequence, the HTML5 form attribute can be the solution.

From http://www.w3schools.com/tags/att_input_form.asp:

1. The form attribute is new in HTML5.
2. Specifies which
   element an element belongs to. The value of this attribute must be the id attribute of a element in the same document.

Scenario:

• input_Form1_n1
• input_Form2_n1
• input_Form1_n2
• input_Form2_n2

Implementation:

Here you'll find browser's compatibility.
