Why won't this line compile?

The compiler hangs at this particular line. No error messages, it just freezes at 5-1/2 bars. If i comment it out, it compiles fine. Leave it active, no compiling. I can't figure out what's wrong with this line. It's worked on other microcontrollers.

Serial.println("%d,%d,%d,%d,%d,%d,%d,%d,%d,%d,%d,%d,%d,%d,%d,%d,%d,%d,%d,", 1024, bv, val01, val02, val03, val04, val05, val06, val07, val08, val09, val10, val11, val12, val13, val14, val15, val16, cksum);

Here's the whole program, if it matters

void setup() {
  // put your setup code here, to run once:
Serial.begin(38400);
}

void loop() {
  // put your main code here, to run repeatedly:
// read the input on analog pin 0:
  int cksum;
  int bv = 12*50; // temporary code until i figure out how to read battery voltage
  int val01 = analogRead(A0);
  int val02 = analogRead(A1);
  int val03 = analogRead(A2);
  int val04 = analogRead(A3);
  int val05 = analogRead(A4);
  int val06 = analogRead(A5);          
  int val07 = 507;
  int val08 = 508;
  int val09 = 509;
  int val10 = 510;
  int val11 = 511;
  int val12 = 512;
  int val13 = 513;
  int val14 = 514;
  int val15 = 515;
  int val16 = 516;
  
  
  // print out the values you read:
  // 1024 is start code
  // bv is battery voltage*50
  // the 16 analog values
  // last is checksum, by adding all analog values together
  
  cksum = (bv+val01+val02+val03+val04+val05+val06+val07+val08+val09+val10+val11+val12+val13+val14+val15+val16);
  Serial.println("%d,%d,%d,%d,%d,%d,%d,%d,%d,%d,%d,%d,%d,%d,%d,%d,%d,%d,%d,", 1024, bv, val01, val02, val03, val04, val05, val06, val07, val08, val09, val10, val11, val12, val13, val14, val15, val16, cksum);
  delay(10);

The eventual platform is an Arduino Mega, which is why there are 16 values. Obviously 7-16 don't work on an Uno, so i gave then constants.

Thanks,
Mike

Leave it active, no compiling

What you are trying to do there does not even make sense. The Serial.print() method does not take that many arguments.

Serial.print() != printf().

If I try to compile your code, I get this ( and then a bunch more scrolling off the pane )
