Another Auto Populate for dates Question

I've had this answered in the past for a similar query. I tried to use a previous script from a different form but i can't seem to make the adjustments for a new, different form.

It's a simple form for dates. I have 14 fields (Date1-Date14). I want to enter the beginning date in Date1 and the rest of the dates auto populate for two weeks.  The script I have seems to duplicate Date1 into Date2 then Date3 is fine. (Enter Date1 as 7/16. Date2=7/16, Date3=7/18). What am I missing so Date2 shows as 7/17?

Here's the script I'm using in "run Custom Validation Script" in Date1:

var date = util.scand("m/d/yy", event.value);
for( var i=2; i<=14; i++){
if(event.value == ""){
this.getField("Date2").value = "";
this.getField("Date"+i).value = "";}
else {
date.setDate(date.getDate() +1);
this.getField("Date2").value = event.value;
this.getField("Date"+i).value = util.printd("m/d/yy", date);}}

I've made several changes but it either duplicates Date1 into Date2 or doesn't complate any of them at all.  I've tried searching the forum but nothing seems to pop up.

Thanks!
