For an college project I require an online calculator that accepts user input (4 variables) and user selections (3 sets of options) and calculates answer based on a mathematics equation (which I will provided). I have a working example but this needs to be extended and I can show equation in excel but need new interface designed. I think a prototype in JQuery or something would work well but open to suggestions... Need to be able to edit text etc. This is really, really urgent so please be aware when bidding, thanks.
