Save choice in database - php

Question

I'm doing a program where I try to save data every time the user press 'submit'. I have managed to save in my table 'answers' the data of the columns: exercise_id_fk, student_id and difficulty_student, but I can not save the data from the column: choice_answer. Every time I try to save it, it stops me from saving the other columns. I'm trying to store in the database multiple choice answers. Can you help me see what is wrong?
This is my program where im trying to store in the column 'choice_anser' from the multiple choice answers:

$result = $conn->query($sql); /*Check connection*/

You have to use the single form if you want to save everything when you click on submit.
<?php
// Start the session
session_start();
$servername = "localhost";
$username = "root";
$password = "";
$dbname = "project";
$conn = new mysqli($servername, $username, $password, $dbname);
/*echo*/ $id=$_GET['id'];
$sql = "SELECT * FROM exercises where exercise_id='$id'";
$result = $conn->query($sql); /*Check connection*/
?>
<div id="centered_B" class="header">
<?php
$row = $result->fetch_assoc();
echo '<h1>' . $row["exercise_id"]. ". " . $row["title"] . '</h1>' . "<br>" . '<p>' . $row["text"] . '</p> <img width="603" height="auto" src="' . $row["image_path"] . '"><br><br>
/*var_dump($id)*/
?>
<br><br><br><!--- Select difficulty --->
<p2>Select difficulty level:</p2>
<form action='' method='post'>
<input type="radio" name="choice" value= "1" /><img src="<?php $row["image_path_A"];?>"/><br>
<input type="radio" name="choice" value= "2" /><img src="<?php $row["image_path_B"];?>"><br>
