HELPPPP!!! OSC AFFILIATE

[Tank27]

i am installing the OSC Affiliate and I keep getting this error

 

Fatal error: Call to undefined function: tep_parse_input_field_data() in /home/www/tank27/catalog/includes/functions/affiliate_functions.php on line 38

 

that is when I click Affiliate login button in the left column. when I go to that file I see

 

// Output a form

if (!function_exists('tep_draw_form')) {

function tep_draw_form($name, $action, $method = 'post', $parameters = '') {

$form = '<form name="' . tep_parse_input_field_data($name, array('"' => '"')) . '" action="' . tep_parse_input_field_data($action, array('"' => '"')) . '" method="' . tep_parse_input_field_data($method, array('"' => '"')) . '"';

 

if (tep_not_null($parameters)) $form .= ' ' . $parameters;

 

$form .= '>';

 

return $form;

 

what am I doing wrong
