I need an online calculator. A customer will enter 2 numbers to receive 2 totals and one of two possible answers (based on if one of the totals is positive or negative). The excel file is attached with the formulas as well as a pdf of the desired appearance and a pdf with appearance notes. I may need to supply our font.
Obviously it should work on all browsers and not require the customer to install anything nor have Excel on their computer. If the customer changes their entries multiple times, the code should simply provide the appropriate answer without the need to refresh the page, etc. We host with [url removed, login to view]
While the formula will not change, we need the ability to alter the amounts the formulas are based on if we change our prices in the future. We want the ability to preform a simple upload to our servers. Thanks so much for your interest.
