We need this changed to php or some other code that will reside on a Joomla based website. We require an AJAX or similar interface that updates as the user inputs data.
There are 5 calculations that are very easy. The formulas are in the spreadsheet. The user enters the data in the light green boxes and the spreadsheet outputs the yellow boxes. Each calculation is individual not related to one and other. It should be the same on the web page
The five areas should be converted so a user can enter the green data and the output is calculated online as calculated as does the spreadsheet.
The text areas on the spreadsheet should be put on the page as text. It can just be paragraphs. I will give you formatting css for those when we finish the project.
The user should not leave the page during calculations or be forced to wait for reloads etc.
We need quick help on this!
