ColdFusion Report Builder

I am trying to use CF Report Builder because the client needs a pretty nicely broken out PDF report.    If I could just get it to output the data, it is going to be VERY pretty.    The code in the current HTML report is

<CFIF isdate(primaryreviewerdate)>#val(datediff("d", PrimaryReviewerDate, now()))#<CFELSE>0</CFIF> Days

Open in new window

This is my translation.  

iif(isdate(query.PrimaryReviewerDate), DateDiff(d, query.PrimaryReviewerDate, getdate()), DE("0 Days"))

Open in new window

Getting the error:   If the expression is a string, ensure that it is within quotes. Error: iif(isdate(query.PrimaryReviewerDate), DateDiff(d, query.PrimaryReviewerDate, getdate()), DE("0 Days")) is not a valid ColdFusion expression.

Anyone have any ideas??

Look at the working example. I simulated the query data, using QueryNew.
            query = QueryNew("ID,PrimaryReviewerDate","integer,varchar");
            tt = QueryAddRow(query, 1);
            tt = QuerySetCell(query, "ID", 1);
            tt = QuerySetCell(query, "PrimaryReviewerDate", "12/1/2014");
            value2=iif((isdefined ("query.PrimaryReviewerDate") && isdate(query.PrimaryReviewerDate)), DateDiff('d',query.PrimaryReviewerDate, Now()), "O days");            
            WriteOutput ("Diff is :" &  value2);

What kind of data field is PrimaryReviewerDate in your query ?
Pravin AsarPrincipal Systems EngineerCommented:
I checked with Date field also. It should work

query = QueryNew("ID,PrimaryReviewerDate","integer,date");
            tt = QueryAddRow(query, 1);
            tt = QuerySetCell(query, "ID", 1);
            tt = QuerySetCell(query, "PrimaryReviewerDate", CreateDateTime(2014,9,24,12,1,0));
            value2=iif((isdefined ("query.PrimaryReviewerDate") && isdate(query.PrimaryReviewerDate)), DateDiff('d',query.PrimaryReviewerDate, Now()), DE("O days"));            
            WriteOutput ("Diff is :" &  value2);

This is in CF Report Builder.   That doesn't work.  I get the same error.

value2=iif((isdefined ('query.PrimaryReviewerDate') && isdate(query.PrimaryReviewerDate)), DateDiff('d',query.PrimaryReviewerDate, Now()),'O days');

Single Quote in lieu of Double quote

Okay. I tried with CF Builder for CF 9

Following worked for me

iif (isDate(query.PrimaryReviewerDate) EQ true, DateDiff('d',query.PrimaryReviewerDate, Now()),DE("0 Days"))
