Hi, following custom form I use as booking- and cancellation-form in an event. When I display my booking for cancellation, I see Field-placeholders like #_COMMENT or #_SPACES rather than the content of these fields. Any ideas? Thank you!

Code for custom form:

<div>
<table class=”table table-sm table-responsive”>
<tbody>
<tr><th scope=”row”>Nachname</th><td>#_LASTNAME</td></tr>
<tr><th scope=”row”>Vorname</th><td>#REQ_FIRSTNAME</td></tr>
<tr><th scope=”row”>E-Mail-Adresse</th><td>#_EMAIL</td></tr>
<tr><th scope=”row”>Anlass</th><td>#_LINKEDNAME am #_STARTDATE um #_STARTTIME</td></tr>
<tr><th scope=”row”>#_FIELDNAME{Anmeldung}</th><td>#_FIELD{Anmeldung}</td></tr>
<tr><th scope=”row”>Reservierte Plätze</th><td>#_SPACES</td></tr>
<tr><th scope=”row”>#_FIELDNAME{Name PartnerIn}</th><td>#_FIELD{Name PartnerIn}</td></tr>
<tr><th scope=”row”>Bemerkungen:</th><td>#_COMMENT</td></tr>
</tbody>
</table>
</div>
#_SUBMIT

What I see when I show my booking, some #_xxxx fields not resolved

Nachname My-Lastname
Vorname My-Firstname
E-Mail-Adresse My-Email

Reservierte Plätze #_SPACES
