My problem is that I need to develop an application with a database and for this I have to manage 3 forms or more  and I am using ajax of jquery to manage data with php  and jquery works very good hiding and showing the different forms, but the problem is that from third form with the button "Enviar" does not work longer overwriting the data that I consult on the div that I want but it returns to the first form and the strange is that with internett explorer works like I want, but I also need that this works with mozilla and opera at least.

so understand better here I send the source code with a simple example without database, only php.
