Stash, Parsingorder (?) and conditionals if content exists

Question

I am sorry to ask this, but I am stuck here.

I must change (on two places) a css class if a channel entree exists. If yes, the class must be unit-70, if no, unit-90. This code below does not work, I do not know why. (when setting stash hardcoded it works as expected)

{exp:stash:set name="content_block_mid" parse_tags="yes" parse_conditionals="yes"}
  {exp:channel:entries
    channel="news_flash"
    disable="categories|category_fields|pagination|member_data"
    dynamic="no"
}
    {if no_results}unit-80{/if}
    {if count >= 1}unit-70{/if}
  {/exp:channel:entries}
{/exp:stash:set}

Can someone please point me in the right direction, obviously I am missing something here. I tried many options, but got lost because nothing works. This seems to me the simpliest of solutions, but I fail even here. Thank you!

Answer 1

Might try using 'unprefix' for the nested channel entry tags:

{exp:stash:set 
    name="content_block_mid" 
    parse_tags="yes" 
    parse_conditionals="yes"
    unprefix="my_prefix"
}
    {exp:channel:entries
        channel="news_flash"
        disable="categories|category_fields|pagination|member_data"
        dynamic="no"
    }
        {if my_prefix:no_results}unit-80{/if}
        {if my_prefix:count >= 1}unit-70{/if}
    {/exp:channel:entries}
{/exp:stash:set}
