Hi Marker Marker,
I have this working fine on a test install that I have on my computer so I’m not too sure why it’s not working for you in the way you need.
What I would say would be best for you to test this out would be to put this code into your template :
{exp:channel:entries channel="work" limit="1" status="New|Open"}
{categories}
{category_name},
{/categories}
{/exp:channel:entries}
This will show you all the categories that are attached to that entry. It may well be that you need to reformat your conditional slightly.
I’m going to move this post on down to the Community Help forums as it’s not really a technical issue as such as ExpressionEngine is doing everything it should be doing however I feel that depending on what you’re doing here you may well need a 3rd party add-on here to get you exactly what you need. I’d highly suggest taking a look over on devot-ee.com to see if there’s anything there that might make this a little easier for you.
Thanks,
Mark
