    Perhaps, but initializing "middle" to (any) one of the input values should work fine too

    I am trying to get the info you are providing, but I am letting the rude comments of Elysia interfer.

    Thanks again,

    I know it may sound like Elysia is rude [he/she may even BE rude], but correctly indenting the code is part of writing good code, so you should really try to understand:
    How to make the editor indent the code correctly and/or why the code doesn't look correct when you post it here.

    The reason indentation is important is that it's showing how the if-statements relate to the actual code.

    Also, I don't actually think you need if-statements "inside each other" (nested if's) to solve this problem.

    Compilers can produce warnings - make the compiler programmers happy: Use them!

    Then maybe I should retort that you are rude to ignore everything I've written thus far, not even a single acknowledgment even that you saw what I wrote but want to focus on something else first.
    Indentation is a very important thing because it makes your code readable.

    Elysia has a lot to offer us all. If Elysia's comments are annoying you, take with 1 grain of salt.

    You do have a nested IF going on there.

    I'm going to simplify the logic. You don't need to have all the variables sorted, just just need to find the middle value.

    This logic will work. See if you can implement this logic:

    if number1 is less than than or equal to number2 AND number2 is less than or equal to number3 then number2 is the middle number.

    else if number2 is less than than or equal to number1 AND number1 is less than or equal to number3 then number1 is the middle number.

    else number3 is the middle number.

    This logic won't work. (Consider number1 = 9, number2 = 7, and number3 = 5.) But the idea is right: to be the middle number, you have to have one number greater and one number less. You need to add the symmetric cases as well (that is for example, number2 is the middle number if either number1 <= number2 <= number3, as given above, or number3 <= number2 <= number1).

    Oops. You're rightll sorry MP.

    (that is for example, number2 is the middle number if either number1 <= number2 <= number3, as given above, or number3 <= number2 <= number1).
    MP, don't interpret this that number1 <= number2 <= number3 is valid C syntax for what you want to do - you had that before, and while we can all visualize and understand what it means, it's not code you want to implement verbatim.
