Creality cr10 thermister and firmware issue

Is there anyone that can meet me up at the space and give me a hand getting my cr-10 running properly, I just added an e3d hot end and thermister and it does not want to work with the firmware I have.

I can bring it up to the space if thee is someone who could meet me sometime would appreciate it.

I have an uno board to help with the firmware installation but I have no idea what i am doing when it comes to this part.
