wp query on checkboxes value

Hello
I’m trying to make a search system based on checkboxes with wp_query. I want to implement the following search:
On a custom post-type “Houses”, look for houses whose area is:
less than 50m2
from 50 to 200m2
from 200 to 1000m2
superior to 1000m2

Area values ??come from checkbox so the user can select one or more values
I made the following request but it does not work, I tried several combinations but it does not work. I get the message “0 result” while there are houses that match the search criteria.
Here is my code:

<? Php
?$ args = array (
???????????????????????????'post_type' => 'houses',
??????????????????????????'posts_per_page' => -1,
??????????????????????????'meta_query' => array (
???????????????????????????'relation' => 'OR',
???????????????????????????????????array (
???????????????????????????????????'key' => 'wpcf-area',
???????????????????????????????????'value' => 50,
???????????????????????????????????'type' => 'numeric',
???????????????????????????????????'compare' => '<'
?????????????????????????????????),
????????????????????????????????array (
????????????????????????????????'key' => 'wpcf-area',
????????????????????????????????'value' => array (50, 200),
????????????????????????????????'type' => 'numeric',
???????????????????????????????'compare' => 'BETWEEN'
??????????????????????????????),
??????????????????????????????array (
??????????????????????????????'key' => 'wpcf-area',
??????????????????????????????'value' => array (200, 1000),
??????????????????????????????'type' => 'numeric',
??????????????????????????????'compare' => 'BETWEEN'
???????????????????????????????),
?????????????????????????????????array (
???????????????????????????????????'key' => 'wpcf-area,
???????????????????????????????????'value' => 1000,
???????????????????????????????????'type' => 'numeric',
???????????????????????????????????'compare' => '>'
?????????????????????????????????)
$ query = new WP_Query ($ args);
?>

Thanks for your help
