I need a calculation mod making for an opencart site. My client sells canvases that can be ordered in any width / height combination from 1" to 80". The calculation for price is (width x height) x 0.something. There are 3 different multiplation values that the (width x height) need to be multiplied by going up in stages as the size of the canvas gets bigger ( I have the full excel spreadsheet with calculations on). I need this mod to integrate on the product template page alongside other standard options (such as choosing the depth of the canvas and the finish etc.) and the client also wants a customer to be able to use select / drop down menus on the homepage and select all options and order from the homepage as well (so the code would need to be translatable to a mod on the homepage (perhaps the html anywhere mod so I can place it in that and then position it anywhere throughout the site).
