SAP Business objects Error: UNV0023

Hi

While creating a @prompt in Derived table i am facing an error called

Parse Failed: Invalid definition (UNV0023). Error parsing mono/multi parameter (7th parameter).

@prompt('Enter the value RVLVG(Start):','D',Revolving merchant/RVLVG Trans Pst date',Mono,Free,Persistent,,User:0) AND @prompt('Enter the value RVLVG(End):','D',Revolving merchant/RVLVG Trans Pst date',Mono,Free,Persistent,,User:1)

So could you please help me out with parsing this in Derived table thanking you in advance

Thanks,

Sunil
