Here's a few hints:

you're trying to fix the code, not change functionality, so you won't need try or catch
check that all variables are declared before they are used (or at the same time they are initialized)
remember that a variable can be declared only once, but it may be assigned many times
check that all variables are declared in the widest scope in which they are used

The issues is that output is created inside of the if statements which limits the variables scope to only being available inside the braces. To fix the issues, initialize the variable before the if statement and remove the initialization that's happening inside the if statement.

Console.WriteLine(output);
