Switch Statement Goes Straight to Default Regardless of Correct Value - switch-statement

Question

/*
Generate a Sales Report:
(+) 1. Use enum to use salespersons' names as values
2. File format with person's last name
-each salesperson gets seperate file (.dat extension)
3. line in file contains item#, last name, and quantity
-1 file created for each item
4. Invalid salepersons' names generate error message
5. Invalid product number generates error message & written to salespersons' file
-don't compute total 4 item then!!!

1. for loop used to loop switch statement
- looped switch statement allows for programmer and user to have more freedom of how
information is inputted/outputted
-for whatever reason wrong information is entered, user/programmer can decide at what point
to start from
-for loop used soley for this utility doesn't allow to start from a special point; for
loops force user through entire loop
-if forced to re-enter information through entire loop, file could be overwritten and/or
contain duplicates

When I select 'Dixon' in as one of the switch values, my switch goes straight to default. I'm using toUpper() and placement() to verify that inputted names exist. How come when I input a name THAT DOES EXIST, it goes straight to default? I input the name exactly as its written in both enum and repname[].
