Webi User Response

Hi Guys,

          In our webi Report we are usIng Date as the Prompt,for that prompt the user can input date in following formats

MM/DD/YYYY and MM-DD-YYYY..Inside the report am catching these dates using the User response..

=UserResponse("Prompt String")..My requirement would be i need to convert them into dates..

For eg: todate(userresponse("Prompt String")"MM/dd/yyyy") this will work for MM/dd/yyyy input format.If suppose the user enters in MM-dd-yyyy am getting #ERROR as message.What can be done  or how it can be done to accommodate both these formats.

Any inputs would be very useful..

Thanks
