Hi there

I have this calculator that is created in excel that i need to somehow convert/put on the web. There are 5-6 input fields. 3 graphs and numerous other output values are generated based on the inputs.

I tried doing a simple "save as web page" with interactive functionality, but that doesn't work. I need people to be able to use this online, without the need for Excel or Office installed. I figure it will take some programming, but does anyone have some pointers on how to get me started?

Thanks in advance.
