so you want to print the same form fields for each iteration on the same
page?

then I would use a method like

echo "<select name=\"record_$count_tyyppi\">"

which results in

<select name=\"record_1_tyyppi\"> for record 1 and so on

and you can access the values in $_POST/$_GET like

$_POST["record_$count_tyyppi"]
