I have been trying to get an icon to become invisible or visible based on whether a property value is between a range within an expression  
this is my code

```auto
if (({session.custom.winddirect} = ( <= 337.5 && >= 22.5 )), ({this.meta.visible} = 1), ({this.meta.visible} = 0))

```

the error\_configuration im getting is Error\_Configuration(“Runtime Exception: syntax error on token: ‘LESS THAN OR EQUAL TO’ (Line 1, Char 38)”)

Additionally, if i replace the less than and greater than value with 0 it gives me a different error saying Error\_CycleDetected I am having a hard time figuring out why this does not work.  
Would greatly appreciate any advice

The `<=` operator needs two values. So you need to supply the value you are wanting to be between 337.5 and 22.5

```auto
if (({session.custom.winddirect} = ( {someValueHere} <= 337.5 && {someValueHere} >= 22.5 )), ({this.meta.visible} = 1), ({this.meta.visible} = 0))
```

I would assume that it would probably mean it is referencing itself. Not sure, where is this binding being used?

Im binding the visible property of an icon and im trying to have the result of the if statement turn the visibility = 1 if within the range or else = 0 if it isnt within the range.  
Yes i am trying to refer it to itself but i cant think of another way to do it

Wouldn’t this expression:

```auto
{someValue} <= 337.5 && {someValue} >= 22.5

```

Accomplish what you want?

Be careful with terminology. Expression bindings are _ **not** _ scripts. They don't support statements or assignments. Just operators and functions.
