Actually code is same in both pages, for form. And what I found was, when first I make search on homepage, using same form, it give results and page/url migrates to env.pl, where same form is present, now when I search again using same form, it works an prints results. But next time, i.e second time on env.pl, it breaks.

I also don't know what is the reason for working at first time, and not working at second time. Now, I am using cg::ajax, so now this is no problem for me, but I would like to hear some reason for it, to increase my knowledge.

thanks for your time
