symbol : variable Convert
location: class HealthProfileTest
double pHeight = Convert.ToDouble(in.nextLine());

Code:

Where is Convert defined?
It's not in this class, or any import...

so you are saying that Im missing Convert in here ??? not sure what you mean

You can't just make up things in Java.
A Convert class or a variable called Convert that is of a class that has the methods you are calling needs to exist.
So, where is it?
That's what the compiler is asking.

it is right here

int year = Convert.ToInt32(in.nextLine());

No, it's not. You're trying to use a Convert class in that line, but this does not mean that you have a Convert class to use somewhere. Again, you can't make stuff up and hope it will work. You either are missing some library from your instructor or your assumptions on how Java works are way off and you'll need to check out the introductory tutorials.
