Hi , i created repeater fields which i display in a select,
i need your help to show or hide a div with my select : in this div there is a a href to dwnlaod my pdf (sub_field), see my code :

<?php if( have_rows('fiche_detaillee') ): ?>
	<form id="diametre"> 
        <select onchange="if(this.selectedIndex == 0)
	{
        document.getElementById('<strong>SER-0,20L</strong>').style.display = 'none';
	document.getElementById('<strong>SER-0,30L</strong>').style.display = 'none';
	}
	else if(this.selectedIndex == 1)
	{document.getElementById('SER-0,20L').style.display = 'inline';
	document.getElementById('SER-0,30L').style.display = 'none';
	}
	else
	{document.getElementById('SER-0,20L').style.display = 'none';
	document.getElementById('SER-0,30L').style.display = 'inline';
	}">
				
	<option selected="selected">Choisissez le ø</option>
			
	<?php while( have_rows('fiche_detaillee') ): the_row(); 
	// vars
	$diam = get_sub_field('diam');
	$pdf = get_sub_field('fichiers_selon_o_');
	?>
		
	<option value="<?php echo $diam; ?>" ><?php echo $diam; ?></option>
		<?php endwhile; ?>	
         </select></form>
		<?php endif; ?>

it work because i wrote the value ‘SER-0,20L’ etc… but i want it’s variable and automatically
and i don’t know how make my script “variable”… you see ?
if i use :

document.getElementById(<?php echo $diam2; ?>).style.display = "block";

it ruturn not all the values, or a multiple script…

SEE the result i want here

Please help !
thanks !
