Need JavaScript written for a travel expense calculator featuring 9 user-defined variables. One field for example, will require users to enter a zip code which will then be converted into 1 of 14 possible numeric values. Some additional fields will require the user to choose from a list of text options which will be also converted into a numerical value.
The HTML page with form fields is complete, as is the formula for how the variables should be calculated. I just need the JavaScript to make the Calculator work.
