нужно чтобы считывало value только из выбраного radio

<input type="radio" name="radio" id="checkbox" value="2830"><span style="color: #677788; font-family: arial; line-height: 20px; text-align: justify;">
      Galileo</span>
        <label for="radio"></label>
        <input type="radio" name="radio" id="checkbox2" value="2810"><span style="color: #677788; font-family: arial; line-height: 20px; text-align: justify;">
      ADM 600</span>
        <input type="radio" name="radio" id="checkbox3" value="1800" onClick="toggle_visibility('Dop')"><span style="color: #677788; font-family: arial; line-height: 20px; text-align: justify;">
      Teltonika 1100</span>

var checkbox = document.getElementById("checkbox");
			var checkbox2 = document.getElementById("checkbox2");
			var checkbox3 = document.getElementById("checkbox3");
            var count = document.getElementById("count");
            var result = document.getElementById("result");
            var price = 0;
			price += parseInt(checkbox.value);
			price += parseInt(checkbox2.value);
			price += parseInt(checkbox3.value);
	    price += parseInt(count.value) * parseInt(result.value);
            result.value = price;
