Answer 1

Pointvalue is string, not integer. how to sum pointvalue, if it is string?
Ok use the same Total Count method you are using, however like this
Name: PointValue
Summary Field: Pointvalue field
Summary Type: Count
Evalution: Each Record
Reset: Group by, Group name
Then place it into the report.
How to use data parameters in report record selection formula?
Ok create two date parameters, static.
One Start Date, Field type (your database field). Value=Date or Datetime (you choose depending on database field type).
Second End Date, Field type (your database field). Value = Date or Datetime (you choose)
Then Click on Report ->Selection Formula-->Record
Type
{database field} >= {?StartDate} and
{database field}<= {?EndDate}
Place both of them into the report header.
Run the report and you will be asked for the dates, once inserted your report will be filtered by date range you entered.
Hope this helps
