Hi!

I would love to get some help with this validation rule: 

I want this Comments field to include Special characters:  . , : ? ; % ( ) & # ' " * - _ 
My Validation formula works for all the special characters except \ backslash and hyphen represents the range in order to consider it as the literal value I need to escape it using two back slashes.


AND (
NOT(ISBLANK( Comments )),
NOT(REGEX( Comments , "[a-zA-Z0-9.,:?;%/()&#\'!\"\"\\-_* ]+")),
)
