Hide row if ACF sub field is checked - php

Question

I got a ACF Reaper field with a couple of rows I am trying to show. However, I only want the show row if it has a checkbox checked (Checkbox is a subfield within the repeater). I am trying to accomplish that by using if in_array as described in ACF documentation under "Conditional logic":
if( in_array( "bestyrelsevalg", get_sub_field( 'bestyrelse' ) ) )
I am outputting the result in a WordPress shortcode. For now, my code kinda works, except it shows all results within the repeater field (also those that are unchecked). What am I missing ??
My code:
function investor_bestyrelse_shortcode() {
$rows = get_field('budgetter_og_nyhedsbreve');
if( $rows ) {
echo '<ul class="slides">';
foreach( $rows as $row ) {
if( in_array( "bestyrelsevalg", get_sub_field( 'bestyrelse' ) ) ) {
$image = $row['upload_dokument'];
echo '<li>';
echo get_field( 'upload_dokument' );
echo '</li>';
}
}
echo '</ul>';
}
}
add_shortcode( 'investor_bestyrelse', 'investor_bestyrelse_shortcode' );

Managed to solve issue and with the help from #maggiathor's answer. For some reason echo was causing issue. I had to use return insted:
function investor_bestyrelse_shortcode() {
$rows = get_field('budgetter_og_nyhedsbreve');
if( $rows ) {
$content = '<ul class="dokumenter">';
foreach( $rows as $row ) {
if( !in_array( "bestyrelsevalg", $row['bestyrelse'] ) ) {
$pdf = $row['upload_dokument'];
$content = $content . '<li>' . $pdf . '</li>';
}
}
}
$content = $content . '</ul>';
return $content;
}
add_shortcode( 'investor_bestyrelse', 'investor_bestyrelse_shortcode' );

You cannot use get_sub_field() within the foreach loop, either you need to use a have_rows-while-loop or access it from the associative array:
function investor_bestyrelse_shortcode() {
$rows = get_field('budgetter_og_nyhedsbreve');
if( $rows ) {
echo '<ul class="slides">';
foreach( $rows as $row ) {
if( in_array( "bestyrelsevalg", $row['bestyrelse'] ) ) {
$image = $row['upload_dokument'];
echo '<li>';
echo $row['upload_dokument'];
echo '</li>';
}
}
echo '</ul>';
}
}
add_shortcode( 'investor_bestyrelse', 'investor_bestyrelse_shortcode' );
