DOH! This is a repeater field, and this works:
`<?php
if(have_rows(‘project_areas’)):
while(have_rows(‘project_areas’)): the_row();
?>
<table>
<tr>
<td>Crash</td>
<td class=”align-center”>
<?php
if( get_sub_field(‘proj_crash’) ) {
if( in_array( ‘Timeliness’, get_sub_field(‘proj_crash’) ) )
{
echo ‘X’;
}}
?>
</td>
</tr>
</table>
<?php endwhile;
endif;
?>’
