Hey there everybody, first of al thank you everyone who helped out with my first question and helped me solve that issue. I have another one for everyone now. So I am trying to make a button component invisible in Vision based on the value of a Boolean tag. What I need for it to do is to be visible when the associated tag is False and invisible when it is True. I tried to script it out, but alas I am still very very new to scripting, and can't quite figure it out. The following is what I scripted in a basic form.

```auto
"""Alpha is the associated Boolean Tag."""
"""Bravo is the Visibility property of the button."""
if Alpha == True:
    Bravo == False
if Alpha == False:
    Bravo == True

```

Is there an easier way to do this, or have I missed something due to my inexperience in scripting?

There is an easier way, just invert the tag value.

If you can use an expression, then use an expression. Scripting is a powerful tool, but it isn't always the best tool to use, and it shouldn't be the first choice.

Use an expression binding:

```nohighlight
!{your tag path}

```

To do this in scripting you would do something like:

```python
Brovo = not Alpha

```

</div>

Also note that `==` does not perform assignment. If for some reason you couldn't use @lrose 's solution, you would have to edit your script at least like so:

```auto
if Alpha == True:
    Bravo = False
if Alpha == False:
    Bravo = True

```

Even better would be:

```auto
if Alpha:
    Bravo = False
else:
    Bravo = True

```

Thank you, I'll apply it to the same button for another unit and when I can connect to the OPCUA server when our test bench is free.

I have your solution @lrose attached to a button for one of two units that are the same design in everything. When the OPCUA server on our test bench is open, I'll test it out.

This made me remember [a comic](https://www.reddit.com/r/ProgrammerHumor/comments/4x26u3/this_is_why_code_reviews_are_a_good_thing/?utm_source=share&utm_medium=android_app&utm_name=androidcss&utm_term=1&utm_content=share_button) that I read some time ago that graphically illustrates why using bools without `==` is typically preferred.
