Referencing values of dynamic tables

Hi All of you!

I'm building a form for one of my clients. It is splitted into three languages depending who fills the form.

One can start from Polish then switch to English and watch everything filled. Another can do the same

but starts from English and follows to pages in Polish. There is also a German part in it.

Previously it was a static form so every value had been propagated between parts of a document

by binding it as Global.

Now I have a dynamic PDF with dynamic tables. I should generate rows of the same table

in each language part and a person who fills can start from any language (part of document).

I'm attaching a small example of two subforms. Each represents different language version. Buttons

of each one can add rows in both tables at the same moment.

I tried to write formulas for the cells to exchange data between. In this example it works. When I import these

subforms into my real document it stops working.

How can I bind values between cells of these tables to work both ways, starting from any of them?

Any part should copy a value from corresponding cells both ways.
