Sorting the report from the browser

[JavidRaj]

Hi
I did create a crystal report template using the desinger without any
group selection.
I can able to view the report using a browser.

I have a html page to view the report, which has various various
parameters in that page for ex:
The page is like this

[check box] Field1 by [radiobutton]ASC [radio]DESC
[check box] Field2 by [radiobutton]ASC [radio]DESC
[check box] Field3 by [radiobutton]ASC [radio]DESC

If I select Field1(as ASC) and Field3(DESC),and submit the page , I can
able to view the report ascending by the field1 and then descending by the
field3.

How can I do this by passing a command to the URL.

right now I'm using the SF command to for the selection criteria
(for ex: ?SF={report.field1} > 100 and {report.field1} < 500).
like this is there any command available for the sorting criteria?
If so could you pls give some example.

Thanks in advance
Raja
