Link on textbox is not working

[mgip]

I try to set a URL on a textbox, but, show the HTML code.

` $fields = array(
'linea0' => 'My name 0',
'linea1' => 'My name1',
'linea2' => 'My name2',
'linea3' => 'My name3',
'linea4' => 'My name4',
'cvs' => 'My city5',
);

    $pdf = new FPDM('/path/template.pdf');
    $pdf->Load($fields, false);
    $pdf->Merge();
    $pdf->Output('F', '/path/to/output.php');`

Anyone?

Thanks
