Hello Scott,

Since you know what most everything else does I'm going to focus on this part of the syntax that repeats itself

@Date-@DOM(@Date)-@DOM(@Date-@DOM(@Date)) 

What this does is it goes to the last day of the month 2 months before the current one. And here is how it does that.

Let's use February 28th 2011 as the current date in this example. So let's substitute that in

2011/02/28 - @DOM(2011/02/28) - @DOM(2011/02/28 - @DOM(2011/02/28)) 

Now let's solve for @DOM() of today's date

2011/02/28 - 28 - @DOM(2011/02/28 - 28) 

2011/02/28 minus 28 is 2011/01/31 so let's substitute that in

2011/01/31 - @DOM(2011/01/31) 

Again let's solve for @DOM()

2011/01/31 - 31 

and we reach the result of

2010/12/31 

Okay now we know that for February 28th 2011 this piece of code below resolves to 2010/12/31

@Date-@DOM(@Date)-@DOM(@Date-@DOM(@Date)) 

So let's substitute that into the original piece of code.

]|@Year(2010/12/31)|/|@Right("00" + @Str(@Month(2010/12/31)), 2)|/..  

Make a bit more sense now?
