    Here's the code I'm working on in functions.php

    function populate_userdrop($form){
    
        //only populating drop down for form id 1
        if($form["id"] != 1)
    
        return $form;
    
        //Creating item array.
        $items = array();
        // Get the custom field values stored in the array
        $meta = get_users();
    
    if (is_array($metas))
    {
    foreach($metas as $meta)  $items[] = array("value" => $meta->display_name, "text" => $meta->display_name);
    }
        //Adding items to field id 1. Replace 1 with your actual field id. You can get the field id by looking at the input name in the markup.
        foreach($form["fields"] as &$field)
            if($field["id"] == 1){
                $field["choices"] = $items;
            }
    
        return $form;
    }

    All I've done on the form is allowed it to be dynamically populated.

    Here's the form in action - http://ethicalincubator.com/BMentor/form-test/

    Wait, did you figure this out? On your form, I see a dropdown with user names in it.

    I AM STOOPID. After debugging I realised I missed the 's' of 'metas'.

    Thanks for the reply. Here is help for anyone else trying this.

    Here's an example of my fully working code to populate a dropdown box in Gravity forms with a list of user display names.

    Add this to functions.php

    // This adds display names for all users to a drop down box on a gravity form.
    add_filter("gform_pre_render", "populate_userdrop");
    
    //Note: when changing drop down values, we also need to use the gform_admin_pre_render so that the right values are displayed when editing the entry.
    add_filter("gform_admin_pre_render", "populate_userdrop");
    
    function populate_userdrop($form){
    
        //only populating drop down for form id 1 - if editing this change to your own form ID
        if($form["id"] != 1)
    
        return $form;
    
        //Creating item array.
        $items = array();
        // Get the custom field values stored in the array
    	// If editing this lookup where you would like to get your data from
    	// this example loads through all users of the website
        $metas = get_users();
    
    if (is_array($metas))
    {
    // in this example we just load the display_name for each user into our drop-down field
    foreach($metas as $meta)  $items[] = array("value" => $meta->display_name, "text" => $meta->display_name);
    }
        //Adding items to field id 1. Replace 1 with your actual field id. You can get the field id by looking at the input name in the markup.
        foreach($form["fields"] as &$field)
            if($field["id"] == 1){
                $field["choices"] = $items;
            }
    
        return $form;
    }

    Yeah, I saw your if statement and was like "where did he define metas?" Glad you got it sorted.
