Display custom field doesn' t work

[nemoprincess]

Hello,
I have three custom field: nome, cognome, regione.

I want display only nome in viewtopic_body.html so I

<!-- IF postrow.custom_fields.PROFILE_FIELD_NAME eq "nome" -->
<b>{postrow.custom_fields.PROFILE_FIELD_NAME}:</b> {postrow.custom_fields.PROFILE_FIELD_VALUE}<br />
<!-- ENDIF -->

and this

<!-- IF postrow.custom_fields.PROFILE_FIELD_NAME eq "Nome" -->
<b>{postrow.custom_fields.PROFILE_FIELD_NAME}:</b> {postrow.custom_fields.PROFILE_FIELD_VALUE}<br />
<!-- ENDIF -->

but it doesn' t work. How can I try? How can I solve? Thank you.
