this is the error on compiling

gcc.exe -c MainRecipe.c -o Objects/MingW/MainRecipe.o -I"C:/Program Files/Dev-Cpp/Include"

MainRecipe.c: In function `insertRecipe':

MainRecipe.c:88: error: invalid operands to binary !=
MainRecipe.c:97: error: structure has no member named `xPtr'


cant understand what is wrong
