What is the exact error? What #include lines do you have in your files? What libraries have you included in the project? If you're getting an error that it can't find a file it helps tell us what file it's looking for.

1. include ""PE_Types.h&quot" that is the line where it says there is an error.

And why are you including PE_Types.h in your code? Is this some project that you are porting to mbed or a project that was already in the mbed system? Posting the code would make it a lot easier to help you.

I got the project off another website but I do not know wether it was ported to mbed or wether it was already in the system.

Could you tell me where to find a simple template for the arduino motor shield? I cant seem to find any good ones. Im new to coding (I started a few days ago) so im not that good.

Well a search on this site for Motor Shield shows up http://mbed.org/users/piniels/code/ArduinoMotorShield/ together with lots of other variants.
