Date value required

Hi Everyone,

I got a report with a date parameter which enables the user to select a single date

however the user selection should pull in the data for the fyscal year by month

so I've created to formulas as follow:

@FYStart:

cdate(year({?Date})

-(if month({?Date})<7 then 1 else 0),7,1)

@FYEnd

cdate(year({?Date})

+(if month({?Date})>=7 then 1 else 0),6,30)

and I've declared the following in the record selection:

{billing_tx_history.date_of_service} >= {@FYStart}

and

{billing_tx_history.date_of_service} <= {@FYEnd}

The report works fine on my local but once I deploy it to the WebApp which is a Web-portal called AVATAR and try to run the report from there I get an error msg saying that:

"Date or number or currency is required here"

and I think the problem that the two formulas above were created using IF function which returns Boolean

Any help would be appreciated
