Hello this is my formula

=IF(VLOOKUP($B3,TB!$B$3:$J$125,9,FALSE)-Week=-37.5,"",IFVLOOKUP($B3,TB!$B$3:$J$125,9,FALSE)-Week)
Week = named ranged for 37.5 (normal working hours in a week) if the
person has not submitted the report I do not want the answer to be -37.50 but
"" (blank) if the person submitted the report and did not work overtime or
worked less than 37.5 the answer should also be blank, if the person did
work overtime then the hours less 37.50 Example hours worked 45.50 so
overtime would be 8 hours . thanks
