I am trying to upload the AFMotor.h to my project and it gives me the error message (exit status 1
#endif without #if) I am not sure what this means. I am new at this

Here is the code I am trying to upload. can someone please help me

Probably needs a #endif there.

Please remember to use code tags when posting code, and this isn't an installation issue

Remember I am new at this. Did you see the code that I sent with it. should what you sent me be at the beginning or the end

Remember I am new at this

Which is why we publish clear instructions on how to pose your questions.

As to your unposed question, "immediately after"

Edit: actually, looking again, probably not.

It looks like you have a failed attempt at an include guard. The correct way to do the include guard is like this:

#ifndef _AFMotor_h_
#define _AFMotor_h_
// code here
#endif

In your code, there is the #define directive twice instead of the expected #ifndef directive, then the expected #endif at the end of the file. That #endif without a preceding conditional directive is the cause of the error.

Is this some code you wrote, or attempted to modify? AFMotor.h is part of the Adafruit Motor Shield Library, but that library does not contain the bug that your code has:

Note that you can't just grab the AFMotor.h file and slap it into your sketch. You need to install the whole library:
