Your code works fine for me.  What's the problem exactly?

Be aware, 'eval' is a built-in function, you might want to use a
different name.  And instead of "your" use "you're" the contraction of
"you are"--  but that's not a code problem.


FWIW, here's another way to structure your program without the
recursion you're using.

yournum = input("I am thinking of a number between 1 and 100.\n  Guess
which number: ")
mynum = (yournum-5)

def loop():
    global yournum, mynum

    while yournum != mynum:
        if yournum < mynum:
            print "Nope.  Too low"
        elif yournum > mynum:
            print "Oh, you're too high"
        again()

    print "Wow!  You got it!"

def again():
    global yournum
    yournum = input("guess again: ")

loop()
