Too few arguments to function

In this bit of code i can not enter more than 6 int's into the parentheses before it says "too few arguments to function"

here is that line of code

void lightLED(int a, int b, int c, int d, int e, int f, int g, int h, int i) {
delay(100);

I think we need more context. The code segment is not complete (there isn't a closing bracket)

maybe you want default values for params?
void lightLED(int a=0, int b=0, int c=0, int d=0, int e=0, int f=0, int g=0, int h=0, int i) {

Usually that message means you are calling it with the wrong number of arguments somewhere else in your app, look for that.
