This was interesting while I wrote the code in, then ran the code
It marked a nice green check mark claiming that it was correct RIGHT!
WRONG, While errors was popping up on the other side. So why is that?

Ran into the same problem.
Don’t initialize the same variable a second time in the same scope.
WRONG:

      // Make camera directions uppercase
      string cameraDirections = cameraDirections.ToUpper();

      // Make scene description lowercase
      string sceneDescription = sceneDescription.ToLower();

Instead simply override the value of the variable.
CORRECT:

      // Make camera directions uppercase
      cameraDirections = cameraDirections.ToUpper();

      // Make scene description lowercase
      sceneDescription = sceneDescription.ToLower();

Hope that helps. :+1:

To be more specific, this is the error: "Program.cs(22,11): error CS0128: A local variable or function named ‘cameraDirections’ is already defined in this scope [/home/ccuser/workspace/csharp-working-with-text-manipulate-strings/e7-workspace.csproj]
Program.cs(25,11): error CS0128: A local variable or function named ‘sceneDescription’ is already defined in this scope [/home/ccuser/workspace/csharp-working-with-text-manipulate-strings/e7-workspace.csproj]

The build failed. Please fix the build errors and run again."

Am I the only one that finds it odd that there asking us to override the value of the variable yet they haven’t taught us how to do so.

Exactly my thoughts. I ended up having the solution being given to me instead of solving it myself. Now I’m sad.

Same problem here. Anyone else?

#8

it might be because you are doing:

string cameraDirections = cameraDirections.ToUpper();

Do this instead:

cameraDirections = cameraDirections.ToUpper();

@Tera504… Well they did, you simply change the value of the variable. Thing that doesnt make sense to me is how the lesson just ends. There was no point to changing the variables, we just did it. I’d of liked for them to have us actually incorporate our work into the script at least… These last two lessons, even though theyre totally free has been a disappointment.
