I think you are looking for URL Parameters. The doc for that is here: http://www.appnitro.com/doc-url-parameters, there is an added step when passing from one form to another.
In your FORM 1, you need to set it to "Redirect to a Web Site" under Form properties. In there, put the full URL (http://...) of FORM 2 AND include the "&element_X_X=" as shown in the documentation. "element_X_X" would be the destination element on FORM 2. Then after "=" use a merge tag to pass FORM 1 info to the designated element on FORM 2.
Using a Name field for example:
Let's say that on FORM 1, the Name field was comprised of "element_1_1" and "element_1_2" ("first" "last") and on FORM 2, the Name field was "element_4_1" and "element_4_2". If you wanted to pass the first and last name from FORM 1 to FORM 2, enter this into the "Redirect to Web Site" box on FORM 1:
http://www.myforms.com/view.php?id=12345&element_4_1={element_1_1}&element_4_2={element_1_2}
(Where "http://www.myforms.com/view.php?id=12345" is the complete URL to FORM 2)
You can add as many as you like from as many fields as you like. I usually put the string in a Notepad file first so I can see all of it and check my spelling, etc. Then just paste it into the redirect box.
Hope this helps!
