The last task for our application is to send all the validated data to a server for processing. We'll use a LoadVars instance to accomplish this goal.

1.	Open validate6.fla. We'll continue building on the project from the preceding exercise.
2.	With the Actions panel open, select Frame 1 of the Actions layer and add the following script at the top of the current script, just below the `stop()` action: var registrationData:LoadVars = new LoadVars(); This creates a new LoadVars instance named `registrationData`. In the next step we will add a script that places our validated data into this instance and sends it to the server.
3.	Add the following script to the `else` leg of the `validateForm()` function: registrationData.name = name_ti.text; registrationData.email = email_ti.text; registrationData.state = state_ti.text; registrationData.zip = zip_ti.text; registrationData.sendAndLoad("http://www.myDomain.com/registration.php",¬ registrationData, "POST"); When all the data entered into the form is valid, the actions in the `else` part of the `validateForm()` functionincluding this section of scriptare executed. The first four lines of the script place the data in the various TextInput instances into the `registrationData` instance. The last line sends this data to a server-side script. Note For the last line of script, you should insert the URL to a script on your server for processing the data. The `else` part of this script already had an action that would send the application to the Confirm label automatically when all the data entered was valid. Because the application is now set up to send data to a server, let's change this functionality a bit so that the application only moves to that frame label after a response has been received from the server, indicating that the submitted data has been received and processed.
4.	Remove the line of script in the `else` leg of the `validateForm()` function that reads `gotoAndStop("Confirm")` and then insert the following script just above the `sendAndLoad()` method call: registrationData.onLoad = function(){ gotoAndStop("Confirm"); } This script will move the application to the Confirm label when a server response has been sent back to the `registrationData` instance. Let's do one final test. Note Before testing, make sure that the URL specified in the `sendAndLoad()` method discussed in Step 3 contains a server-side script for handling the incoming data.
5.	Choose Control > Test Movie. If you enter valid data into the form fields and click the Submit button, the application should send the data to the specified server-side script for processing, and eventually move the application's Timeline to the Confirm label after a response has been received from the server.
6.	Close the test movie to return to the authoring environment, and save this file as validate7.fla. This step completes the exercise and this lesson. The great thing about the way we set up this project's validation process is that it's dynamic. To analyze additional rules or validation points for any of the text fields, all you have to do is add more conditional statements to the appropriate function. The validation process can grow as your needs grow.
