Remove price from specific collection but leave on others Dawn theme

Store Design

I’ve followed various posts’ advice and nothing will work for me, I can remove prices from all collections but preferably I’d remove price showing on only one. I had some success but it only works on desktop view and the mobile device does not change?

Any help appreciated.

enclose the price output with the following code

{% if collection.handle =='name-of-collection' %}
NOPRICE
{% else%}
PRICE
{%endif%}
