We are losing a partner and I have to adjust the schedule. Rather than rewrite or edit 10 scripts I want to be able to simply update the main week day schedule table then advance forward in the main table and have the fields update.
Sounds like you are specifying literal data in the script that should be stored in a record of a table. If that data were in a table, you would find and edit the table and your script then runs as needed without having to modify the actual script.
"Look up" means different things in different contexts. You might be performing a find for data or copying data from the filed of a related record into the corresponding record of another. And in other contexts, that might just be a dynamic link to the related data so that updates happen automatically.
So please clarify exaclty what you mean by "look up".
