How to concatenate values with criteria that must fall within 2 dates?

Hello folks,

How can I concatenate values with criteria that must fall within the specified dates? I tried to use the stringconcat formula and combine AND with IF to cover the criteria that must fall within the specified dates but it did not give me the expected result.
Anyone, please help. Attach is the file. Kindly check & correct my formula in cell B3.

Thanks in advance
