Hi,

i am just trying to understand why the field within a group is not showing, i think this will need a special code ! i searched everywhere and couldn't find the solution!

here is my code: the first line shows normally the value, but the second doesn't show the value for another field within a group
```
<?php
echo rwmb_get_value('select_u6xr9smqot_k9abafij1m');

echo rwmb_get_value('group_b30kbpp4roh_select_u6xr9smqot');
?>
```
i copied the id from inspector

thanks for your help

Hi,

The value returned when getting the field group is an array, so you need to loop over the array by using foreach. Please follow this documentation to know how to display the group value
https://docs.metabox.io/extensions/meta-box-group/#getting-sub-field-value

Thanks alot,

here is my working code
```
<?php
$group_value = rwmb_meta( 'group_b30kbpp4roh' );

$value = isset( $group_value['select_u6xr9smqot'] ) ? $group_value['select_u6xr9smqot'] : '';
echo $value; // Display sub-field value
?>
```
