forms are gone

[Disco_Inferno]

Okey, this might me a the noobiest question ever but I still ask it. :)

I want to make a flash/php form to login. I know my php and how to use it so thats not the problem here. The problem is that I can find the forms to add to my flash project.
On my right side of the flash program screen I see a box that says"components". This holds the radiobutton, pushbutton and so forth. But there is no normal form bar here.
Anyone can tell me how to add this?

I`m using flash MX.

Thanks a lot allready.
