Next, in your table where the user is adding these orders, I’m assuming like an orders or line items table etc… add a field for the sales guy to enter the ‘Height’, Width and Product.
add a “Rollup” field in whatever your parent table is (assuming an invoice or invoice line items table)
Let me know if you have any other quesitons or issues doing this. Keep in mind you can add multiple filters like where height is great than x and lower than x etc…
