Ms Access 2007 (bound information)

We have a database in Ms Access 2007. We need to bound a multi box selection with a table in order to filter some information in order to filter some data. We need that depending on the selection on sppId, spcId and cppId the system will automatically filter the information in frm_pry_cpi_spi We also need to bound frmProyect with proyCod in frm_pry_cpi_spi The idea is that user can filter based on selection, delete or create information in frm_pry_cpi_spi
