I understanding about setting up the tables and I set up the relationships.  I built a StockT Table with the following fields:

ID(Automumber)
FirstName
LastName
StockName
Quanity
StockPrice

Just for clarification, what I need to do is change the StockPrice on one particular kind of stock if possible with one function.  Because there could be 50 customers with the same stock.  I know that there is a find and replace function, but that won't work when the price and the stock name are two separate fields (columns). So are you saying that the two separate fields(which are 2 columns) can be bound together by a third column?
Sorry, but with my inexperience I just need to clarify this.

Thank you much!
