Cause
The expression referenced in the error message ends with an operator. Examples of operators are (but not limited to):
- Boolean (AND &&, NOT !)
- Mathematical (addition +, subtraction - , etc)
- Greater Than ( > ) and Less Than ( < )
Resolution
Complete the expression according to the proper syntax of the formula or function. The error message will tell you the character position of the operator char(n), and which expression contains the error (Expression #). There will be a red squiggly under the exact position. In the older tool interface, clicking Go at the bottom right corner will put your cursor in the correct location.
