What is the mass defect of the 15N nucleus?

My attempt:

15-7=8
7(1.008665)+8(1.0078225)-14.003074
=1.120161

the answer needs to be in u so i dont know if this makes a difference or not but for some reason it is not working

Why are you using the number 14.003074? That's the mass of 14N. The mass defect is the real mass (of 15N) minus the mass of the constituent neutrons and protons.
