Hi,

The error message "Use parentheses when calling functions or indexing variables. Otherwise, check for unmatched delimiters" suggests that there is an issue with the syntax of the function call.

To resolve this error, make sure that any function calls or variable indexing in the function are enclosed in parentheses when necessary. Check that all opening and closing parentheses, brackets, and braces match correctly.

Thanks
