Hi Nick,
Thanks for the reply, I will go through link and see if I can fix the problem I'm having. but I'm sorry I'm not sure what you mean by code Tags. but this is one of the errors I'm receiving:
C:\arduino-1.0.1\libraries\ballistics_solve.c: In function 'SolveAll':
C:\arduino-1.0.1\libraries\ballistics_solve.c:5: error: 'GRAVITY' undeclared (first use in this function)
C:\arduino-1.0.1\libraries\ballistics_solve.c:5: error: (Each undeclared identifier is reported only once
C:\arduino-1.0.1\libraries\ballistics_solve.c:5: error: for each function it appears in.)
I hope that helps. Please let me know if there was anything else that I forgot to include.
Thanks,
Jason
