(Lesson 2) I'm following along with Patrick but solidity flag an error in my code despite it being the same as instructed

You've declared the variable favouriteNumber twice. I'm guessing the second time was supposed to be an assignment not a declaration.
To be sure, please share you code and I'll give you the correct fix for your problem.

Identifier means the name of the variable. If you use a different identifier -- or, name -- this should be fixed; because you cannot declare something which was already declared.

If your intentions are to change the value of the previously declared identifier, just remove the primitive data type (in this case, uint256 and int256).

The above is initialization, whereas when you assign a primitive data type to the identifier, that is declaration.
