I have the code below that I want to change so that it can search for values ​​in the database on the field ID.

Form B contains (Form ID 11)
name
last name
permission (Field ID 89)
CVR (unique)

Form A contains (Form ID 12)
CVR (unique) (Field ID 117)
name
last name

When form A submitting, I will look for already created forms in form B, which contain the CVR number.
take the CVR number from form A and add it in the permission field in form B.

Help :)

Start your code here
add_action('frm_after_create_entry', 'update_or_create_entry', 30, 2);
add_action('frm_after_update_entry', 'update_or_create_entry', 10, 2);
function update_or_create_entry($entry_id, $form_id){
    if ( $form_id == 12 ) {//Change 12 to the ID of Form A - ID 12 = firma - tilknyt kunde
         global $wpdb;
         
		 $CVR = $_POST['item_meta'][117]; 
    	 $total = "test13";
         
         $form2 = '11';//Change 11 to the ID of Form B - ID 11 
         //Get user and their total
         $user = $wpdb->get_var($wpdb->prepare("SELECT user_id FROM {$wpdb->prefix}frm_items WHERE id=%d", $entry_id));
         if ( !$user ) {
             return;
         }
         //$total = FrmProStatisticsController::stats_shortcode(array('id' => 87, 'type' => 'count', 'user_id' => $user));//Change 47914 with the ID of the field that you want to total
 
			 
         //See if this user already has an entry in second form
         //$entry_id = $wpdb->get_var("Select id from {$wpdb->prefix}frm_items where form_id='" . $form2 . "' and user_id=". $user);
         $entry_id = $wpdb->get_var("Select id from {$wpdb->prefix}frm_items where form_id='" . $form2 . "' and item_key=". $CVR);
         if ( $entry_id ) {
             //update entry
             $wpdb->update( $wpdb->prefix . 'frm_item_metas', array('meta_value' => $total), array('item_id' => $entry_id, 'field_id' => '89'));//Change 48262 to the ID of the field you want to populate in Form B - 89 = 
         } else { 
             //Do nothing
               ),
             ));
         }
  }
}
