I've found those useless. But, some of how to implement this depends on your design. Are the four questions displayed on a single form? If so, you can requery the dropdown and remove any item previously selected.



>Greetings All,

>I am working on allowing my users to setup their username, password and also (4) security questions. How do I do the following:
>
>a. Once the user selects their first question, remove that question from all the subsequent available questions. For example,
>
>Available questions in the sec_quest.dbf table are:
>What is your Mother's Maiden name?
>What school did you attend?
>When did you graduate from high school?
>What is your favorite color?
>What is your favorite car?
>
>b. The user selects a question from the first combo box, What is your favorite car?. Then they answer the question, and the second combo box enables with the remaining questions:
>What is your Mother's Maiden name?
>What school did you attend?
>When did you graduate from high school?
>What is your favorite color?
>
>And so on, and so on.
