Ok here is your code:
$rs = mysql_query("INSERT INTO app (name,company,address,state,post,phone,fax,email) VALUES ('$name','$company','$address','$state','$post','$phone',$fax','$email')");
$result = mysql_query($rs);
=====================================
Here is my modification.. well use this below instead:
$rs = "INSERT INTO app (name,company,address,state,post,phone,fax,email) VALUES ('$name','$company','$address','$state','$post','$phone',$fax','$email')";
$result = mysql_query($rs);
=====================================
What you had it doing is this:
$result = mysql_query("mysql_query("INSERT INTO app (name,company,address,state,post,phone,fax,email) VALUES ('$name','$company','$address','$state','$post','$phone',$fax','$email')")");
