Dear SA Thuy,
Thank you so much for explaining, but i am affraid this is not my competention, meaning it doesn't mean anything to me.
I went to that default and followed your instructions in edit-settings- file- choose a editor- and than i completely lost my way.
Is this the only way or is there a method that's easier and more comprehensible by me?

Dear A Brouwer,

You can click on default.php file( /domains/cadeautjeworkum.nl/public_html/templates/sj_gifts/html/mod_sj_minicart_pro/default.php), click right-mouse, choose View/Edit with Notepad, find (ctr+F) the code, edit and Save. FilleZilla will ask you to update the change or not, and you click OK.

Thanks
