I am still designing a purchase order form for automotive sales and now have
a new question.

For example, if I have a ZPP Premium Package that includes a list of options
that has its own codes, i.e. ZPP = 319, 4NA, 430, 431, 403..... how can I
get Excel to automatically pick up ZPP if I receive a full list that have
other options?

For example, I have an automobile that has the following list of options:

205, 465, 319, 203, 4NA, 4AB, 430, 431, 639

How can I get Excel to recognize that ZPP is part of this list?

Your assistance (again) is greatly appreciated.
