    Hey, thanks a bunch for all your help!
  2. DCrawshawJr
    Yeah, that was something I tried to figure out. So, if on my INPUT tags, I had the same id value, how would I be able to use the getElementbyId method to be able to clear the fields all at once?

    Oh...now I see the problem. Every fourth account is being read. Continuing to debug...
  5. DCrawshawJr
    Wait...scratch that previous post. It was the wrong snippet of code. And the getElementsbyTagName does work, I found out. Still working on it...

Plus, while I know it's not good programming style, I'm having a fixed number of accounts for the sake of simplicity, so I could just get the bare bones code to work.

    I'm using Chrome...and I've got some studying to do. The regular debt payment is self-explanatory as shown in your version. The logical approach I was taking in the debt snowball method was such: 1. Clear the snowball variable, and reset the payments. 2. Find any loans that are paid off in the previous loop. 3. Transfer each of those payments to the snowball variable. 4. Transfer the totals to the next lowest loan. 5. Make a payment. 6. Charge interest. 7. Repeat until all loans are paid off or this loop repeated 999 times. As for the "a" variable, I wasn't aware that I had to declare that in a for loop. Like I said, I've got some studying to do with your version. Thanks!

    I used Notepad++ in part of it, and I'm not sure how to check for errors. I did get rid of the main do loop. Now, I was mainly guessing with this code: balance[a] = parseFloat($("#balance"+a.toSring()).val());interest[a] = parseFloat($("#interest"+a.toString()).val());payment[a] = parseFloat($("#payment"+a.toString()).val()); I'm thinking that's where some of the syntax errors are. What I was trying to do was, within the for loop, plug in the number version of the string texts onto the variables. Anything different I can do? Also, how would I return the r_months variable and s_months variable on the actual HTML upon clicking "Calculate" without JQuery? Thanks again.

    Hello everyone! I need some help with a program I wrote in JavaScript. It is designed to tell you how many months you have to pay off your loans, given your balance, interest rate, and monthly payment of up to ten loans. It shows you the number of months it will take to pay off the loans with regular payments, and with the debt snowball method. I'm trying to convert this from a program I wrote in FreeBasic, but I'm having some trouble getting it to work. Some code was borrowed from another guy, such as the beginning tags, but the actual program idea is mine. Thanks! Here's the code (warning: long): <!DOCTYPE html PUBLIC “-//W3C//DTD XHTML 1.0 Transitional//EN” “http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd”><html xmlns=”http://www.w3.org/1999/xhtml”><head><meta http-equiv=”Content-Type” content=”text/html;
