Reports select all not working

Parameters:MemberTypeId,FullName,ActiveActive Parameter Properties:->Allow Multiple Values->Available Values:Active=0, Inactive=1Query:select UserId,FullName,Active from dbo.Users where MemberTypeId=@MemberTypeId and (Active=@Active) and (((FullName like '%'+@FullName+'%' or @FullName IS NULL) and @MemberTypeId=1) or @MemberTypeId=0)So the active will be a dropdown of Select All, Active,Inactive.Active and Inactive works but not select all. I would like to have an option of select all where it displays all active and inactive.
