date range search script - Filemaker Pro

I have a database. it has three buttons that are meant to do date range seacrhes. Two of them do, but I cannot get the All Units button to work. It displays the dates and under each date it shows the unit and what each unit needs. However I cannot get it to search within a date range. If i use the same script as the other two it will not work with that layout. But if it get the layout to display correctly it will not allow me to do date range search. I just need the script tweaked so it will allow me to do that for the All Unit button on the scene details page. thanks
