WEBI prompts and Filtering

Question

Hi all,
I am new to BO and I am working in BO XI R3.
I have to create a WEBI report which will have two prompts.
1.first prompt is based on AMOUNT column in my report eg: Amount(LOV): $55000 
2.second prompt is not based on any column in the report or universe. but it should accept the value from the user eg: Range value: $3500
The result should show all the rows that are having Amount>= $51500 (i.e $55000-3500) and Amount<=$58500 (i.e $55000+3500) 
Can any one suggest what steps I need to follow in webI or designer to get this type of results.
Thanks!

Thanks for your reply
I tried these steps. 
1. I created an object Named "Range Value" and put @Prompt('Enter value','N',mono,free,not_persistent,)  in where condition in the universe.
2. In webi report I dragged this "Range Value" object in the query filter panel and selected it as prompt and put prompt message as 'Enter value'.
3. After I run the query I am getting an error as "A database error occured. The database error text is: [Microsoft][ODBC SQL Server Driver][SQL Server]Statement(s) could not be prepared.. (WIS 10901)".
4. I tried to change the prompt message in query filter as 'Enter a range value' and run the query. this time it prompted me with 2 prompt messages
a.Enter value (the Prompt message which I gave it in the object in the universe):
b.Enter range value(the Prompt message which I gave it in the query filter panel):
5. when I entered same values in both the prompts again it was throwing me the same above error.
6. Later I tried to put 'Enter a range value' prompt as optional and then run the query. this time I entered value in only one prompt and it worked. BUT the problem is that it shows 2 prompt Messages.
7. I repeated same procedure to create another prompt "Enter Amount" and the same thing happen 2 prompt messages
a."Enter Amount"
b."Enter Amount value"
How can I avoid showing 2 prompt messages for one object?
I avoided that and created all below variables in the webI report
a.v Amount = ToNumber(UserResponse("Enter Amount"))
b.v Range = ToNumber(UserResponse("Enter value"))
c.v Max Amount = v Amount + v Range
d.v Min Amount = v Amount - v Range
now when I was trying to filter the report with Max Amount and Min Amount I am not able to select the variable in the WEBI filter panel. It only gives me LOV of that columns.
Where I am going wrong?
how can I avoid 2 prompt messages for one object and how to filter the amount with min and max values.
Can you please explain me more in detail.
thanks,
