Time Field won't consistently insert into Database

[sweetp]

I have an applet (I got off the web) that lets a user pick a span of time to reserve a room, and I can pass that info to the next .jsp page to view the choice. However, when I use the Insert Record command in Dreamweaver to insert the time into an Access database, sometimes it works, but most times it locks up the database (causing an .ldb file that won't close). I have the Insert Record behavior format for the field set to "Date MS Access".

Any ideas why it won't accept the time into the database? If I leave it out, then everything else inserts fine (user name, room name, etc.) ????????
