I have a database of products and cost of goods sold. At this point I would like to break the numbers down further. Ideally I would like to have (either in a different layout, or seperate database) a way to take e.g. 5 lbs. and $23.00 and push a button which could break those numbers down into cost per teaspoon, cost per quart...etc. I will use this to get my idea cost of goods sold for menu items at my coffee shop. Any ideas or suggestions? Should I make it a seperate database using portals to connect the two? How do I build the calculations? I was thinking of a pop up list of measurements with a script for calculating by whichever measurement I chose. How could I build such a beast?
