Value of all buttons having the same ID?

MySQL

I am using an update SQL statement to update the MYSQL database, however, each button seems to be bringing back the same ID (The first ID of the first item displayed on the page) I have echoed each MealID and each is correct, so there must be something wrong somewhere that isn't getting different IDs for each button.

See my code below. Can anyone see the problem here?

-Loop to display items with buttons.

What I have tried:

-Loop to display items with buttons.

while($dbRow=$dbQuery->fetch(PDO::FETCH_ASSOC) and ($cnt < $max)) 
{
  echo "".$dbRow["Name"]."".$dbRow['Picture']."' width='150' height='150'/>"."<br><br>".$dbRow["Instructions"]."

<form method='POST'><input type='hidden' name='MealID' value='".$dbRow['MealID']."'><input type='submit' name='submit' value='Complete'>";

//UPDATE SQL STATEMENT - (getting SAME value for each button)

$value = $_POST['MealID'];
//var_dump($value);

if(($_POST['MealID'])) {
$dbQuery=$conn->prepare("UPDATE Users SET Display = 1 WHERE 
UserID=:UserID AND MealID=$value"); 
$dbParams = array(':UserID'=>$UserID);
$dbQuery->execute($dbParams);
}
