Neil,
Thanks for the help.  I believe I have corrected all the errors however a
huge mess at run-time.  again, not sure what direction to take, if you could
be so kind as to give your feedback (or anyone else for that matter)

Thanks again (code below)

char ID[noOfStudents]; // array of ID's (strings)
double Grades[noOfStudents][noOfGrades]; // array of 5 arrays each of 3
elements (each student has 3 double grades)
double GPA[5]; // array of gpa's (doubles)
float points;
int j;
int i;
for (i=0;i=noOfStudents-1;i++)
