Нужно скрипт вывести сложение двух чисел в инпут
Есть два инпут радио value="40" и value="90"
и есть инпут id="metr"
Нужно вывести в инпут id="summ"
инпут id="summ" = инпут id="metr" * радио value="40" или "90"
в зависимости от выбора инпут радио
<div
class="calculator">
<inputname="radio-531"type="radio"value="90">
<inputname="radio-531"type="radio"value="40">
<inputid="metr"name="text-167"size="40"type="text"value="">
<input id="summ"
name="text-882"
size="40"type="text"
value="">
</div>
Как должно работать:
вводим число в ипут id="metr"
и ипут id="summ" отображается умножение ипут id="metr" на ипут радио
