Simple but hard to figure out

[islandgirl23]

Hello, I have a button on my form and I want it to operate like this:

1.  When you click the button, it asks you for a password.

2.  If the password is entered correctly, a date field box appears and it allows you to enter information in it.

3.  After the information is entered in the date field box, the button in #1 above, is hidden.

4.  If the password is entered incorrectly in #2 above, then nothing happens. 

Is there a script or scripts that can make this work?

Your help in this is appreciated.  Thank you.
