Missing ; error message

I am trying to make a PDF for school fees automatically calculate when the user enters the number of children in each department (P, H or N). I thought I had the code figured out, but I am getting an error message stating "missing ; before statement 3: at line 4" and it highlights the line I made red. I tried adding a ; at the beginning of that statement, but the error message did not change. Any help would be greatly appreciated.

var c2 = 1950; var c3 = 2150; var c4 = 2350; var c5 = 2550;

var children = this.getField("P").value + this.getField("H").value + this.getField("N").value;

var full = this.getField("P Calc").value + this.getField("H Calc").value + this.getField("N Calc").value);

if (children > 4) {

event.value = Math.min(full,c5);

} else if (children > 3) {

event.value = Math.min(full,c4);

} else if (children > 2) {

event.value = Math.min(full,c3);

} else if (children > 1) {

event.value = Math.min(full,c2);

} else {

full;

}
