I Try to manage something like this, but the sub_field “zusatzbutton” doesn’t work.
Any thought?

<?php
		$seite = get_field('seite');
		$zusatzbutton = get_sub_field('zusatzbutton-check');

		if($seite) {
		  echo '<div class="seiten grid-3 wrapper">';
		     foreach($seite as $s) {
		         echo '
		         <div class="seite column">
	              <div class="seite-bild"><a href="'.$s['button-link'].'"><img src="'.$s['seite-bild'].'"></a></div>
	              <h2>'.$s['seite-text'].'</h2>
	              <a class="weiterlesen" href="'.$s['button-link'].'">'.$s['button-text'].'</a>';
               
               		if($zusatzbutton == 'yes') {
               			echo '<a class="weiterlesen" href="'.$s['zusatzbutton-link'].'">'.$s['zusatzbutton-text'].'</a>';
               		}
               		
		         echo '</div>';
		     }
		  echo '</div>';
		}
	?>

You can’t use get_sub_field() unless you are in a have_rows() loop. https://www.advancedcustomfields.com/resources/have_rows/

This will return an array of rows

$seite = get_field('seite');

where each element of the array is a row with nested elements for each field
example representation of this value:

$seite = array(
  array(
    // row 1
    'zusatzbutton-check' => 1, / some value for this sub field
    'second-sub-field' => 'value of this field',
    // etc... 
  ),
  array(
    // row 2
    // etc...
  )
)

Have rows loop

if (have_rows('seite')) {
  while (have_rows('seite')) {
    the_row();
    if (get_sub_field('zusatzbutton-check')) {
      // show information about this row
      // for more information see the link provided for have_rows()
    }
  }
}
