asking for user's input before report generation - plz help?

Hi guys,
I am very new to Rep Services so need your help or suggestion:
Question: Let's say I have a very simple set of data, but before the
report is generated, userviewing the report has to enter a number and
then the report takes this number and subtracts from it a number
sitting in the database - and displayes the result in the report.
Let me explain. Let's say here's my data:
Item Bill
1 $30
2 $50
3 $45
Before the report is generated, a popup will come up, asking the user
to input a Total Bill on Paper Invoice $.
Then the report will show:
Internal Total: $125 (this is the number calculated from the data
table.
Total Bill on the Paper Invoice: $130 (this is the number that the
report viewer inputted)
TOTAL AMOUNT DUE: ($130) - ($125) = $5 (this is the difference
between user's inputted number and the number from the table.
How would I create a report such as the above so that prior to report
generating, a popup would come up asking for the user to input $130 and
then the report would take the difference between user's input number
and the number sitting in the database table?
This should be very easy, but since I'm so new, I need your help.
Thanks in advance.The HTML report header can't pop-up a window to prompt users for input but
you can use a parameter that will show-up in the header toolbar. Add a
report parameter and then reference it in an expression as (textbox value)
=Parameters!TotalBill.Value-Fields!InternalTotal.Value
