A form populates a table from form entry with a unique ID. After the submit button is clicked, it creates a file where you can save and print. It works perfectly but when an entry is edited, any subsequent entry doesn't create a new file but rather update the last entry. In other words, the unique ID doesn't increase anymore unless the system is relaunched.
Below is the function for my create button

$('#create_btn').click(function () {
		$('#create_invoice').get(0).reset();
		$('#action').val('create_invoice');
		$('#title').text('DONATION');
		$('#action_create_invoice').val('Donate');
		$('#invoice_items').empty();
		calculateTotal();
