извините, поторпился:

send_btn.onRelease = function() {
	my_vars = new LoadVars();
	my_vars.company = company_box.text;
	my_vars.name = name_box.text;
	my_vars.sender = email_box.text;
	my_vars.subject = subject_box.text;
	my_vars.message = message_box.text;
 
	if (company_box.text != "" && name_box.text != 
		"" && email_box.text != "" && ssubject_box.text != "" && message_box.text != "") {
		my_vars.sendAndLoad("mailer.php", my_vars, "POST");
	}
};
