Multiple forms on Opera

Hi everyone:
I'm having a problem runing search page on opera. the page consists on 3 different forms(one for each type of search). The problem is that only the first form shoes well on opera, and the rest are located far away to the right and not viewable. The page works fine on IE and Firefox. I was wondering, maybe there is some kinf of trouble with opera handling multiple forms. Well, hope someone has the answer. Greetings....

Can we have a link so we can see the page?

Unfortunately the peoject is still on developement stage and is not yet running on the server. I guess I could post the code, it's a bit messy. I'll put just the part I'm interested on resolving, it's quite long.

I know, I should get rid of that tabled layout, well, it has not been written by me, I'm just reviewing it.

I just tried it in both IE6 and opera and looks the same ...
