Syntax Error on Token

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

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

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

Thank you lrose i think that resolved it but can you tell me what is meant by cycle detected or how i can work around it

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

Thank you lrose i figured it out i just took out the self.meta stuff and replaced it with 1 and 0 and it works, i realise what cycle error is now

Wouldn’t this expression:

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

Accomplish what you want?

Yes, it has been accomplished i am not fluent in how to structure my scripts, yet but with your help i am one step further. Thank you again for your time.

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