Hide a field in a list (in runtime) depending on a selection in another field

Hi,

I'm starting to work with Nintex forms and have one problem.

I would like to hide a field (e.g. NameA) if the user choose in another field e.g. NameB the value `BP`or FP or FL

it means: if NameB contains BP or FP or FL the field NameA doen't appear in the formular.

I tried some different rules:

Condition:   contains (NameB, 'BP') and check the hide Icon -> this works fine, but this is only one choice and I need BP, FP and FL

then I tried : equals .... and not.... but it didn't work (I'm not sure if I use this in the right form)

Have someone an idea how I can do this?

Regards

Andrea
