This error indicates that there is a naming conflict with a variable that has already been declared in the Fox formula.
  Cause:

  Check Variable Declarations: Review the Fox formula for any duplicate variable declarations. Ensure that each variable name is unique within the scope of the formula.

  Review Scope: Ensure that you are aware of the scope of your variables. If you are using nested blocks or functions, make sure that variable names do not conflict across these scopes.
  
  
  Use Descriptive Names: To avoid future conflicts, use more descriptive variable names that are less likely to overlap with others.
  
  
  Test Incrementally: If you are making changes to a complex Fox formula, test your changes incrementally to identify where the conflict arises.
