hi there.
I'm not sure how you're sending the mail via html? are you simply opening up the default mail client on the user machine, rather than using PHP or ASP to handle it without opening the mail client.
if so, if you're using AS2 what you can simply do it with a mailto.
where str would be set to the value in the form, which i'm assuming is recipient in your code.
submit_btn.onRelease = function()
{
var str:String = "
[email protected]";
getURL("mailto:"+str);
};
