your checkboxes both of name agregados[], makes them array. handle them via implode, later foreach.

before mail, run foreach this

if (!empty($_post['agregados'])) {     foreach ($_post['agregados'] $key=>$value) {         if ($key > 0) {             $agregados .= ", $value";         } else {             $agregados .= "$value";         }     } } else {     $agregados .= "(nothing selected)"; } 

this set variable $agregados values selected checkboxes, , if nothing selected, display such message instead.

then, in mail, replace line handles checkboxes variables.

replace:

 incluir en la cotizacion: " .implode(',',$_post['agregados'])."\n" . " 

with

$agregados 

also, please know mail sent regardless when enter contactoformescritorio.php, there no checking if form has been sent it. check performing (if ($_server['request_method'] == "post")) comes after that.

---

as final note, not 1 that's related question directly, select has no require-attribute, php script exits if nothing selected (where checking of 1 of 3 statements empty). put required attribute in select, such this

<select class="size" name="tamanio" id="cd-size" required> 

then seleccionar tamaño can set line this

<option value="" selected style="display:none;">seleccionar tamaño</option> 

this make form more "user-friendly", , not make user fill in form on again if forget select dropdown. tip, nothing have do.
