Ok, here is real hard one...granted the last one wasn't! I figure this is going to involve Logic Functions.

This is a basic invoicing system that has a table for the invoice, line items, and products. In the products database I have a feild for Category, Sub-Category and Manufacture.

In the invoice layout, I want the user to select Category (which will be an auto generated value list) choose an option...that will then eaither open, or simply reduce the number of available sub categories available in the next menu. Once he selects a sub-category, he'll then be able to do the same to the Manufacture...untill finally he is presented with a list of products from that manufacture from that sub category from that category....

Does this make sense?

Basically, right now, the value list is generated from all hte products...a list of like 600 items...need to slim down the selections.

Take a look at this posting earlier today.
