Build a really simple program

I have a list of numbers for example: 12-85-13 12-125-15 18-85-17 18-125-13 I want to be able to count the first number, (12, 18, whatever) put in the measurement for length, width and height and have it tell me the size 12-85-13 the amps and the kwh. See attached for example. This is a WEB BASED platform to go on a plain site. Just a simple website nothing fancy needed where I can type and get the answers. I will give you a data list with about 200 sizes. I will give you a domain name to set it up with.
