  A variable that is supposed to accept only a single value (e.g., a characteristic that should only have one selection) is set up to allow multiple values or ranges.

  Check Variable Settings:
  
  Open the Query Designer and locate the query that is causing the error.

  Ensure that the variable is set to "Single Value" instead of "Multiple Values" or "Interval".
  
  
  
  Adjust Query Logic:
  
  If the variable is intended to allow multiple selections, consider changing the logic of the query to accommodate this. You may need to adjust the way the variable is used in the query or change the design of the query to ensure it aligns with the variable's configuration.
  
  
  
  Test the Query:
  
  After making the necessary adjustments, save the query and test it to ensure that the error no longer appears.
