Making a feedback form in flash is EXTREMELY easy. The first one will be tough, but once you understand the concept you will be satisfied.
Basically, set up your form in flash with your fields (the fields are text areas, only they are set to "Input Text"), and give each text field a Var name.
Once you set up your form, create a button that will have the following code executed when pressed on:
function submitForm(){
loadVariablesNum("http://www.yourdomain.com/yourScript.asp")
}
The yourScript.asp page could be whatever you want it to be, PHP, ASP, whatever. This page will be set up in the same way you would set it up if an HTML form would be submited to it.
Let me know if you can get past this part. I will explain the rest when you do so.
