Sorted this myself.
For the record I have created a shortcode.php file and called it from functions.php
It was quite easy once I understood. This is the type of code I used
function cultivar_name() {
if(get_field(‘cultivar’)){
$field_name = “cultivar”;
$field = get_field_object($field_name);
echo ‘‘, $field[‘label’],’‘ . ‘: ‘ . ‘<div class=”headlinename”>’, $field[‘value’],'</div>’,'</br>’;}
}
add_shortcode( ‘cultivar’, ‘cultivar_name’ );
