You're close, but the challenge wants you to combine "Hello " with the name in the function and have it return that.

You also won't need to "print" anything for this challenge.

You need to combine the two strings using concatenation, with a + sign instead of a comma. And you need to add a space to keep the words separate:

    return "Hello " + val

Also, you could skip creating the extra variable and just use the parameter directly in the return expression.

def hello_student(name):
    return( "Hello" +  name )

Almost there, but you still need to add a space to keep the words separate (see my example).
