Extract data with one criteria and no duplicate

Dear All,

If i want to exctract data from worksheet "LIST" in column Item with certaint criteria in column Month and show the extracted data with no duplicate in worksheet "ectdata" starting from cell B7, is it possible to do this task with VBA? So everytime we change the criteria in worksheet "ectdata" on cell B4, tha list will be change accordingly.

For more detail I attach the Excel data.

Thank you for your kind helping.
