Hello

Anyone can help with error for report pdf

Fatal error: Uncaught TypeError: Unsupported operand types: float - string in C:\xampp\htdocs\openemr\vendor\mpdf\mpdf\src\Mpdf.php:9842 Stack trace: #0 C:\xampp\htdocs\openemr\vendor\mpdf\mpdf\src\Mpdf.php(10009): Mpdf\Mpdf-\>\_puthtmlheaders() #1 C:\xampp\htdocs\openemr\vendor\mpdf\mpdf\src\Mpdf.php(2047): Mpdf\Mpdf-\>\_enddoc() #2 C:\xampp\htdocs\openemr\vendor\mpdf\mpdf\src\Mpdf.php(9507): Mpdf\Mpdf-\>Close() #3 C:\xampp\htdocs\openemr\interface\patient\_file\report\custom\_report.php(903): Mpdf\Mpdf-\>Output(‘chris\_kokou\_1\_r…’, ‘D’) #4 {main} thrown in C:\xampp\htdocs\openemr\vendor\mpdf\mpdf\src\Mpdf.php on line 9842

I have applied this solution and nothing done after the line 60 of custom\_report.php:

$config\_mpdf[‘margin\_top’] = $config\_mpdf[‘margin\_top’] \* 1.5;  
$config\_mpdf[‘margin\_bottom’] = $config\_mpdf[‘margin\_bottom’] \* 1.5;  
$config\_mpdf[‘margin\_header’] = $GLOBALS[‘pdf\_top\_margin’];  
$config\_mpdf[‘margin\_footer’] = $GLOBALS[‘pdf\_bottom\_margin’];

Basically you add 4 lines to `openemr/interface/patient_file/report/custom_report.php` right after `$config_mpdf = Config_Mpdf::getConfigMpdf();` so you will get :

```auto
if ($PDF_OUTPUT) {
    $config_mpdf = Config_Mpdf::getConfigMpdf();
    $config_mpdf['margin_top'] = $config_mpdf['margin_top'] * 1.5; >
    $config_mpdf['margin_bottom'] = $config_mpdf['margin_bottom'] * 1.5; >
    $config_mpdf['margin_header'] = $GLOBALS['pdf_top_margin']; >
    $config_mpdf['margin_footer'] = $GLOBALS['pdf_bottom_margin']; 
    $pdf = new mPDF($config_mpdf);
    if ($_SESSION['language_direction'] == 'rtl') {
        $pdf->SetDirectionality('rtl');
    }

```
