Dear johnH-8
Try use this code:
<a href="[types field="tape-url" output="raw"][/types]" onclick="ga('send', 'button', 'click', 'download ');" onkeypress="this.onclick">[types field="tape-title"][/types]</a>
Please let me know if you are satisfied with my answer and if I can help you with any other questions you might have.
Regards,
Marcin
