Passing field values from one FormBuilder form to another

[cisco]

Hi,

I'm rebuilding one html site to CMSMS platform and have small problem.
I need one small form to pass field values to another FormBuilder form.

For example what I need please open this page:
http://www.eurocargo.co.yu/en_wir_uber_uns.html

Just fill out anything and click the "further >" link.
Small form will pass values to the bigger one.

If somebody can help out, help would be greatly appreciated!!
Tnx a lot.
