Simple Form - New User

I am looking to create a simple Access Database. It needs to do the following:

The employee needs to be able to scan (enter) in their ID into a field

After that field is entered another field displays their name (based on the value entered in the ID field)

Next there is a predetermined list of Job assignments that the employee can select from

Last there is a time stamp.

All of this data is then entered into a master table.

That's it.

Nothing (I assume) to hard. I have been looking all of the internet for help and have been working in access all day. If anyone could lend some expert advice, I would appreciate it!

Thanks
Erich
