How do I fix the segmentation fault error in C

I am new to C and I can't figure it out. The code compiles and lets me run it one time but when I enter it gives me segmentation fault. I ran gdb and backtraced it to find that the segmentation fault was in int main () in commissionOfAMechanic (name, &percent); but I don't know how to make it work. If someone could give me any types of suggestions to fix that error. The files I used in the code are in the bottom.
