520 Server error when trying to pass form data to php variable

Hi Guys,

i'm still new with chronoforms and have stumbled upon a problem while trying to pass a value to a php variable on form load.

I have a form which i am using to edit user details, on this form i have a link which will open a modal allowing me to email the user directly. However i cannot seem to pass the user_id to a php variable. It is appearing in the array on page load as:

Array
(
    [cont] => lists
    [ccname] => leadinfo
    [act] => edit
    [gcb] => 42
    [leadinfo] => Array
        (
            [id] => 42
            [uniq_id] => 
            [user_id] => 1001
            [created] => 2015-05-15 12:44:11
            [modified] => 2015-05-15 11:44:11
            [s_type] => 1
            [fname] => Annette

            [button6] => Submit
            [hidden66] => 
            [addinfo] => None
        )

    [user] => Array
        (

            [params] => Array
                (
                    [editor] => none
                    [timezone] => 
                    [language] => 
                    [admin_style] => 
                    [admin_language] => 
                    [helpsite] => 
                )

            [lastResetTime] => 0000-00-00 00:00:00
            [resetCount] => 0
            [otpKey] => 
            [otep] => 
            [requireReset] => 0
        )

    [id] => 42
    [user_id] => 1001
    [created] => 2015-05-15 12:44:11
    [modified] => 2015-05-15 11:44:11
    [s_type] => 1
    [fname] => Annette
    [lname] => Curtain
    [school] => Leicester
    [class] => Street-Smart
    [t_num] => 0123456789
    [email] => name@email.com
    [activity_status] => 0
    [t_date] => 18-05-2015
    [conf_call] => 1
    [taster_conf] => 1
    [taster_attended] => 0
    [t_dns] => 0
    [button6] => Submit
    [hidden66] => 
    [addinfo] => None
)

Now i want to pass the user_id field value (value is 1001 in this instance) to a variable called $userid but whatever im doing is wrong as everytime i try and assign it and output it through FirePHP, i refresh the page and am faced with a Server 520 error. What would be the correct way to assign this value to the variable?

Thank you in advance.

Woohoo....it always seems that as soon as i post i find a solution. The solution is to use the model id also, i just found it hidden in some faqs when using google to search instead of the in built search function.

$userid = $form->data['model_id']['input_name']

Just in case anyone else has a similar issue.

Best Regards
