Flash form for loging in (easy)

I just started playing with flash. I designed a stadard username / pass entry box conected to php:
---------------------------
Username | |
---------------------------

---------------------------
Password | |
---------------------------

The two things that I can not figure out are:

1. When I enter data into the first box and hit <TAB>
It only highlights the next box it does not let me enter text without clicking in the box.

2. I cannot find any text that enters the password as stars. Is the a way of doing this in flash?

Any help is appreciated.
Thanks,
Neal

Problem n° 1 :

Selection.setFocus(my_first_field);

// tab's management
var i=0 ;
i++
my_first_field.tabIndex = i ;
i++;
my_second_field.tabIndex = i ;
i++;
and_so_end_field.tabIndex = i ;

Problem n° 2 :

In the text field property window, you can choose : 'password'
and if you do that , only stars appear.

answer me if this help you. (I dont well understand english)
Good luke

The second one worked great. Thank you.
I don't quite understand the first on though.
Is the code exactly like it should be entered? and where do I put it Under the frame or one button or both? Are the names of my button the instance name or the var name?
Thanks for your help,

and Under the frame or one button or both?
Thanks for your help,

Is the code exactly like it should be entered?
->The code is exactly the same ,except the variables's names .

where do I put it ?
->I already put this kind of code (with a stop() after). in the first frame of the clip where was my text instance.

Are the names of my button the instance name or the var name?
->It's the text instance's name.
NB:
I never use the var name of a text-field in my programm, I prefer use the instance's name. example :

my_text_occurence.text = "hello" ;
// and not :
my_text_var_name = "hello" ;
