Blank fields are shown, ssrs report based on date field, MS CRM 2013 Online

Hi,

1. List of opportunities whose expected close date is within next 15 days

2. List of opportunities whose expected close date is between next 15 days to 30 days.

3. List of opportunities whose expected close date is between next 30 days to 45 days.

For the first report "expected close date is within next 15 days" i got the proper output  - as i have prepared the XML query with the filter as "Next 15 days".

but for the other two reports , since we cannot take dynamic direct query of 15-30 days or 30-45 days, I have prepared the XML query with the filter as "Next 45 days" and created the field expression in ssrs as below:

--- expected close date is between next 15 days to 30 days---

=IIF(((Fields!estimatedclosedateValue.Value >= DateAdd(DateInterval.Day,15,Today) AND (Fields!estimatedclosedateValue.Value <= DateAdd(DateInterval.Day,30,Today) ))), (Fields!customerid.Value)&" ("& FormatNumber( Fields!new_projectedordervalueindollar.Value,0)+")", nothing)

---expected close date is between next 30 days to 45 days---

=IIF(((Fields!estimatedclosedateValue.Value >= DateAdd(DateInterval.Day,30,Today) AND (Fields!estimatedclosedateValue.Value <= DateAdd(DateInterval.Day,45,Today) ))), (Fields!customerid.Value)&" ("& FormatNumber( Fields!new_projectedordervalueindollar.Value,0)+")", nothing)

But the report is shown with blank rows in between where the condition is not satisfied. I have tried the row visibility property as well to hide the blank fields, but no success.
