Hello  
i am trying to show a image field when a particular value is selected

```
    test_name = fields.Selection([
    ('dft', 'DFT'),
    ('adhesion', 'Adhesion Test'),
    ('color', 'Color'),
    ('visual', 'Visual'),
    
    ], "Test Name")

image = fields.Binary('Image', states = {'invisible': Eval('test_name') != 'dft' or Eval('test_name') != 'adhesion' })

```

i tried the above code but it does not seems to work

any heads up where am i doing it wrong ?

In the PYSON expression I think you need to use a `|` instead of `or`.

However, I still don’t think that will work because it looks like your expression will always evaluate to true, so you might want to use `and` instead of `or` and you do this with the `&` operator.

… and

- you should add [`depends=['test_name']`](https://docs.tryton.org/projects/server/en/latest/ref/models/fields.html#trytond.model.fields.Field.depends)
- you could use the [In](https://docs.tryton.org/projects/server/en/latest/ref/pyson.html#trytond.pyson.In) operator like this `~Eval('test_name').In_(['dft', 'adhesion'])`
