Hey there... i'd be very grateful if you could point me in the right direction here:

i've followed the instructions on how to dynamically populate a field in the form by using a query (in functions.php)... and it works fine... I have this form on a post with certain "custom fields/meta values"... and am populating the form with the same... so, i do it for one of the fields like so...
```
[php]
add_filter('gform_field_value_city', 'populate_city');
function populate_city($value){
    global $post;
	$city = get_post_meta($post->ID, "city", true);
    return $city;
}
```
where my parameter name is "city"... and also my custom field name is "city" too... and it works... now i repeat the same thing two more times to get two more custom field values...
```
[php]
add_filter('gform_field_value_country', 'populate_country');
function populate_city($value){
    global $post;
	$country = get_post_meta($post->ID, "country", true);
    return $country;
}

add_filter('gform_field_value_region', 'populate_region');
function populate_region($value){
    global $post;
	$region = get_post_meta($post->ID, "region", true);
    return $region;
}
```
so... that's three in all... "city", "country" and "region".... and when i do this... it ives me a blank screen... if i remove two of the three... and leave only one.. anyone... it works... but doesnt work for more than one...

can you please help me out here...

never mind... there seemed to be a problem with a "typo" or rather wrong name... in one of the lines... this works now:

[php]
add_filter('gform_field_value_city', 'populate_city');
function populate_city($value){
    global $post;
	$city = get_post_meta($post->ID, "city", true);
    return $city;
}

add_filter('gform_field_value_country', 'populate_country');
function populate_country($value){
    global $post;
	$country = get_post_meta($post->ID, "country", true);
    return $country;
}

add_filter('gform_field_value_region', 'populate_region');
function populate_region($value){
    global $post;
	$region = get_post_meta($post->ID, "region", true);
    return $region;
}

all 3 fields get populated the right way... thank you though... and i'll be back if theres something else i get stuck with...
