Dynamic Value Lists

[SES Tech]

I still can't get my head around this. Could someone "cookbook" this for me? I get confused going to Define DB, Relationships, Value list, Field behavior, etc.

I want to script/calculate which values of a ClassID (table of classes) will show in a drop down. Sometimes it will be only for a specific grade, sometimes All, sometimes, not yet assigned classes. [i've read most of the posts, here, but when I try it, nothing happens - I must be omitting some step]

Thank you

Have you read these?

I think i cookbooked it pretty well in the first post (if i do say so myself). I could work up a version 7 attachment if you think you need it. What is not working out, or what is unclear, when you follow those steps?
