Xpath as Grid data source

Hi All,

I am trying to use something like below in my data grid with Xpath as data source. I need to check if a datetime attribute lies between a certain value. But below does not work at runtime. Could anyone please help

[eventDate >= 'parseDateTimeUTC(formatDateTimeUTC($ImportSet/EventDate,yyyy-MM-dd),yyyy-MM-dd)']
[eventDate<'addDaysUTC(parseDateTimeUTC(formatDateTimeUTC($ImportSet/EventDate,yyyy-MM-dd),yyyy-MM-dd),1)'
]

Import Set is my input
