2 forms in a page

Hi,
during my experiences with scrybt I faced a problem with a web page with two forms. Submit uses the last form.

HOw is it possible to submit the first one or how can I control this problem. I tried it with submit (index), it doesn't help!
I tried like this:
submit "/html/body/table/tbody/tr[4]/td[2]/div/div/div[3]/form[1]"
It is the same, the second form is the same.
In the forms there is not any text_field to be filled.
I attach a copy of the html page and my ruby code.

I would like understand how can I control this to work with this tool.

Thanks for help...
