Dear sir,

I used below VBScript function inside XSLT. I found example and description 
on microsoft site. However it always return below errors.  Any helps?

{"Microsoft VBScript runtime error
Wrong number of arguments or invalid property assignment
line = 6, col = 2 (line is offset from the start of the script block).
Error returned from property or method call.
"}

 function comparedate(fromdate,todate)
    if fromdate = "" or todate = "" then
      comparedate = "yes"
    else
        if cdate(fromdate) > cdate(todate) then
            comparedate = "yes"
       else
           comparedate = "no"
       end if

  end if
end function
