❔ issues with variable

I have this variable called "remChar" var remChar = Console.ReadLine().ToUpper(); while (remChar == "YES" || remChar == "Y") I want to access the variable later on in the while loop so I can change the information in the variable to look for if it says "No", but when I try to implement it into the code it says " A local or parameter named 'remChar' cannot be declared in this scope because that name is used in an enclosing local scope to define a local or parameter" How would I go by using the variable later on in the code? thank you :)

sounds like you tried to redeclare the variable i.e. you wrote var remChar = newValue; instead of remChar = newValue;

is it possible just to use the variable again? because i tried to do remChar(); and it had an error "Method name expected"

well remChar isn't a method so you can't call it using () You can use the variable again by just assigning it a new value.
