So I have put in my bash script in shell check and I'm getting this error code which says:
 

Line 61:

function print_2() {

^-- SC1009 (info): The mentioned syntax error was in this function.

                   ^-- SC1073 (error): Couldn't parse this brace group. Fix to allow more checks.



 

Line 164:

manage_users;

             ^-- SC1056 (error): Expected a '}'. If you have one, try a ; or 

 in front of it.

             ^-- SC1072 (error): Missing '}'. Fix any mentioned problems and try again.

I'm having a hard time getting rid of the error message and finding the problem, I've tried making changes but I'm getting the same error message and I was wondering if any of you could help me find the problem.
