PHP script to Increment value in mysql - php

Question

I am trying to design a scoreboard for a project for my local youth club and would like to be able to click a button onto a wordpress page that will run a PHP script to update a value by 1 in a sql db table, then i can grab the value and display it else where.
Not too worried about passwords being used in scripts at this will only be used within the local network that nobody else has access to, have looked around and found a few bits of code but im not able to actually get it working, here's what i've got so far.
<?php
$servername = "localhost";
$username = "username";
$password = "password";
$dbname = "sot";
// Create connection
$conn = new mysqli($servername, $username, $password, $dbname);
// Check connection
if ($conn->connect_error) {
die("Connection failed: " . $conn->connect_error);
}
$sql = UPDATE wp_sotstats SET CaptainChest=CaptainChest+1 WHERE id=1
if ($conn->query($sql) === TRUE) {
echo "New record created successfully";
} else {
echo "Error: " . $sql . "<br>" . $conn->error;
}
$conn->close();
?>
The database name is 'sot' the table i want to update is called 'wp_sotstats' and the field within the table is 'CaptainChest' i only need this to really work with just the one entry which the id is '1'
Any thoughts?

$sql = UPDATE wp_sotstats SET CaptainChest=CaptainChest+1 WHERE id=1
if ($conn->query($sql) === TRUE) {
echo "New record created successfully";
Is not creating record, it updating it. For me, I will take current value from database as Select, then do ++ to it and do Update query.
$sql = UPDATE wp_sotstats SET CaptainChest=CaptainChest+1 WHERE id=1
Please wrap it in quotes and finish statement with semicolon
