Multi set body page usage based on dates

[Mike]

Eric has been kind enough to help me work out the following age based code and I have to say it works brilliantly to turn on and off the back pages only for printing.

My question is how would I tell fusion to turn on and off both a front page and a back page. I am a noob and just can't get it to work. Below is the code that works perfect

Code that works:

// OnRecordStart
Date.prototype.YearsBetween = function(){
var intMilYear = 365.23 * 24 * 60 * 60 * 1000;
var intMilDif = arguments[0] - this;
var intYears = Math.floor(intMilDif/intMilYear);
return intYears;
}

var dob = new Date(Field("birthday")); // YOUR FIELD in a standard date format
var today = new Date();
var yearsBetween = dob.YearsBetween(today);
// Turn on age related backs for specific record (Pages named A,B,C,D and set to Unused)
if (yearsBetween <=16) FusionPro.Composition.SetBodyPageUsage("BackA",true);
else if (yearsBetween <= 40) FusionPro.Composition.SetBodyPageUsage("BackB",true);
else if (yearsBetween <= 60) FusionPro.Composition.SetBodyPageUsage("BackC",true);
else FusionPro.Composition.SetBodyPageUsage("BackD",true);

What I need help with in red

// OnRecordStart
Date.prototype.YearsBetween = function(){
var intMilYear = 365.23 * 24 * 60 * 60 * 1000;
var intMilDif = arguments[0] - this;
var intYears = Math.floor(intMilDif/intMilYear);
return intYears;
}

var dob = new Date(Field("birthday")); // YOUR FIELD in a standard date format
var today = new Date();
var yearsBetween = dob.YearsBetween(today);
// Turn on age related backs for specific record (Pages named A,B,C,D and set to Unused)
if (yearsBetween <=16) FusionPro.Composition.SetBodyPageUsage("BackA",true) + FusionPro.Composition.SetBodyPageUsage("FrontA",true);
else if (yearsBetween <= 40) FusionPro.Composition.SetBodyPageUsage("BackB",true) + FusionPro.Composition.SetBodyPageUsage("FrontB",true);
;
else if (yearsBetween <= 60) FusionPro.Composition.SetBodyPageUsage("BackC",true)+ FusionPro.Composition.SetBodyPageUsage("FrontC",true);
;
else FusionPro.Composition.SetBodyPageUsage("BackD",true) + FusionPro.Composition.SetBodyPageUsage("FrontD",true);
;

Any help would be great.

My bad (sort of). I kept all the IF statements as one-liners since my example was only returning a single result per condition. In your case, you want to run 2+ commands so you need to place them on separate lines inside curly brackets "{}" as follows:
// Turn on age related backs for specific record (Pages named A,B,C,D and set to Unused)
if (yearsBetween <=16) {
FusionPro.Composition.SetBodyPageUsage("BackA",true);
FusionPro.Composition.SetBodyPageUsage("FrontA",true);
}
else if (yearsBetween <= 40) {
FusionPro.Composition.SetBodyPageUsage("BackB",true);
FusionPro.Composition.SetBodyPageUsage("FrontB",true);
}
else if (yearsBetween <= 60) {
FusionPro.Composition.SetBodyPageUsage("BackC",true);
FusionPro.Composition.SetBodyPageUsage("FrontC",true);
}
else {
FusionPro.Composition.SetBodyPageUsage("BackD",true);
FusionPro.Composition.SetBodyPageUsage("FrontD",true);
}
On another side note, if you enclose your JS code with the CODE tags, it will place your code in an interior gray box making it a little easier to separate code from general text in a forum post. The CODE tags are found in the WYSIWYG text editor denoted by the pound sign, or you can just surround your code with (code](/code] (replace left parenthesis with left square bracket).

Thanks mate, your help is greatly appreciated.
