It worked! Another related question:
How would I go about adding ALL attachments from the input?
This is what worked:
=HYPERLINK(“{{1.custom_fields.Reklamationsunderlag.url}}”, “{{1.custom_fields.Reklamationsunderlag.title}}”)
The attachments are part of an array and I want all array items or 1, 2, 3, 4. Is there any way this can be done simply? I’ve made a separate post about this.
