pulling from database to textbox on frontend

[thatkidval]

Hello All,
This is my first post here...... So, i have a web form that takes in clients info, sends it to a database on the server. Now, i want to be able to create a textbox where the corresponding number on the database will come up when the client clicks enter...........

Example, client name, date, time, blah, they hit enter and they get this message.................your order has been successfully entered, your order # is "#".

this is my problem, thanks in advance
