I have two questions:

1) In the second line of the formula below, what does the following text mean? &nv=2&v0="

2) Similarly, in the third line, what does this text mean? "&v1="

var text datewords = ToText(FirstDayOfMonth(AdjustMonth(Today(),0)));

var text URL = URLRoot() & "db/" & [_DBID_TIME_CARDS] & "?a=q&qid=145&nv=2&v0="

& ToText($datewords) & "&v1=" & ToText([Company:Project]);

var number Value = [Billable Hours Current Month];

var text Words =

If($Value >0,

ToText(Int($Value ))

& "."

& If(Int($Value )=$Value ,"00",

Length(Right(ToText($Value ),"."))=1,Right(ToText(Frac($Value )),1) & "0",

Right(ToText(Frac($Value )),".")));

"<a href=" & $URL & ">" & $Words & "</a>"
