Hi,

If you needn't the extra arguments, please leave the second argument empty.
```
function query_crm_usados_interna(){
 $meta = rwmb_meta( 'if_usados_usad_id', '', get_the_ID() )
return $meta;
}
```
Get more details in the documentation https://docs.metabox.io/rwmb-meta/#arguments.

Hi,

If you do not use the function in the loop, just add a parameter to the function like the helper function.
```
function query_crm_usados_interna( $post_id ){
 $meta = rwmb_meta( 'if_usados_usad_id', '', $post_id )
 return $meta;
}
```
then pass the post ID when calling the function
```
echo query_crm_usados_interna( 1234 );
```
