Java Help I am trying to create a program where when the page loads, a prompt pops up and asks pick a number 1-5 for a shape, then 1 or 2 prompts pop up after that and then ask about either height, length or radius etc. I want those variables to be put in a table and then i want the variables to be put through a set of equations so it can determine the volume, area, etc. I am confused right now, this is as far as i have gotten but now i am stuck and dont know what to do. Suggestions? btw the prompt that goes:
figure = prompt("Please Select a figure from the following list (enter a number):", "1");
dont worry bout that i will add the 5 shapes to that prompt later. Quote:
