Hi!

We have a form field where we want to only show the members who have a special task. So, for example, the Kassa field we only want the people who have a task to operate the Kasse.
I\'m not sure if you can see the link, because it's only for logged in people. I have an attached file here as well. We did have a PHP snippet who made it possible, but if I activate this we have a fatal error on the forms. 
(*I can't upload a PHP file here, so see in the bottom off this message)

So can you look why the PHP snippet is not working or how we can make this work?
Thanks already!
