You say that you want to add the average cost, which is located in the first table, to the results from table 2. And that for each item in the second table, there is an item in the first table that matches.
The way you set up the arrays is very uncommon and may not be what you want. The data structure you choose depends in part in what you want to do with the results. Just print them out to a report, perform calculations on them, etc. By looking at the fields you're capturing, these seem to be business statistics. It would be helpful to know what it is you want to do with the results. If each of the variables you set up equaled the number of returned fields, there are about 21 of them.
