Hi, I have some knowledge of HTML and Javascript but am a little unsure of how exactly to go about doing what I want or where to start.

I have used Photoshop to create a mockup of what I am trying to achieve.

Basically I already have the information that I want, I want to be able to select a dropdown box and then it autofills the text boxes with information.

At the very bottom of it all I want to perform a calculation with simply adds all the information from column 1 and then the same for column 2 etc etc.

I hope someone can point me in right direction or even offer some assistance.

Thank you, please ask any questions.

Here is the picture of my end goal.
