I found an article online about how to change it, but it doesn’t work and I dont understand why

and did you assign it as the preferred search form on the roles tab?

and did you add your fields as filters, or criteria?

yes I did hit the double carats down

@KevinJ of Kansas is it supposed to be form or results?

No other boxes checked.

Search form should be the field that drives it

Although I'm looking at your setup

and I think I see an issue - you have it defined as the global preferrred search form and results - but you then also applied role specific

In general when I see someone do something like that, it breaks. So i would suggest unchecking it from your role specific lines

Feel free to share more screenshots of your results/filters page - maybe something will jump out at me, but if you've done all that, only thing I can imagine goofing you is needing a cache refresh - see if it works in a different browser.
