No problem.
Below is the code I am using to grab a random selection from a repeater field (‘after_options’).
<?php
$options = get_field( 'after_options', 'option' );
if( is_array( $options ) ) {
$option = array_rand( $options );
$signupHTML = $options[$option]['html'];
}
?>
<div class="signupAfter">
<div class="signupText">
<?php echo $signupHTML; ?>
</div>
<div class="signupForm">
<input type="text" name="fname" class="fname" placeholder="First">
<input type="text" name="lname" class="lname" placeholder="Last">
<input type="text" name="email" class="email" placeholder="Email">
<span class="button">Subscribe</span>
</div>
</div>
