Complete Password Generating Application?

I'm currently working on an application with the following guidelines and need some help with completing it:Create an application that allows the user to enter a password that contains five, six, or seven characters. The application should create and display a new password using the following three rules:

1) Replace all vowels (A,E,I,O,U) with the letter X.

2) Replace all numbers with the letter Z.

3) Reverse the characters in the password.

Also included in the guidelines:

1. Instead of using the textbox to accept user input, please enable users to enter the original password in an Inputbox.

2. Users should be able to enter 3 original passwords.

3. Display all three new passwords in a label, one in each line.

So far I have managed to get the application to create a password but I'm not sure how to make it repeat 3 times using the Inputbox and then display them in a label.code]...
