Hi everyone,

I'm building a beer appreciation website and need help with a public code that I found on the web.

The code is for a blood alcohol content calculator and it currently reads the same message after 0.08. I'd like to offer different messages within more specific paramaters, such as 0.04 to 0.08, 0.08 to 0.12, 0.12 to 0.16, etc.

Ideally, in the future I'd like to be able to add multiple drink sources with different alcohol % values, but the parameters would be helpful for now.

I'd appreciate any help anyone can offer, thanks!

<!-- TWO STEPS TO INSTALL BAC CALCULATOR:

1. Copy the coding into the HEAD of your HTML document
2. Add the last code into the BODY of your HTML document -->

<!-- STEP ONE: Paste this code into the HEAD of your HTML document -->

<HEAD>

<script LANGUAGE="JavaScript">
<!-- Original: James P. Dildine (jpd@wlsmail.com) -->
<!-- Web Site: http://www.mste.uiuc.edu/dildine -->

<!-- This script and many more are available free online at -->
<!-- The JavaScript Source!! http://javascript.internet.com -->

<!-- Begin
function solveBAC(form) {
var ounces = eval(form.ounces.value);
var percent = eval(form.percent.value);
var weight = eval(form.weight.value);
var hours = eval(form.hours.value);

var result = (ounces * percent * 0.075 / weight) - (hours * 0.015);
if (result < 0) {
message = "There is a negligible amount of alcohol in your system. You are not legally intoxicated.";
result = "-- neglible amount --";
}
else {
if (result == "NaN")
mesage = "Please try again.";
if (result > 0.08)
message = "In MOST and possibly ALL states you would be considered intoxicated and arrested for DUI.";
if (result < 0.08)
message = "You are not legally intoxicated";
}
form.message.value = message;
form.bacamount.value = result + " %";
}
// End -->
</script>
</HEAD>

<!-- STEP TWO: Copy this code into the BODY of your HTML document -->

<BODY>

<li>HOURS CONSUMING DRINK</li>
</ul>
</td>

You need to change this bit
CODE
if (result > 0.08)
message = "In MOST and possibly ALL states you would be considered intoxicated and arrested for DUI.";
if (result < 0.08)
message = "You are not legally intoxicated";


to a series of tests like this.
CODE
if ((result > 6 )&&( result < 8 ))
message ="some blah bla";


Also, it's more common to use 'else if' than just a series of 'if'.

CODE
if (some condition)
  {
    // do someting
  }
else if (another condition)
  {
    //do something
  }
else if (yet another condition)
  {
    //do something
  }
else  (last condition)
  {
    //do something
  }

Thanks for the help, pandy!

With some tweaking and patience, I got exactly what I needed from your more common "else if" suggestion.

Take a look at the result: http://www.bestbeerbuzz.com/BAC-Calculator.html

Thanks again!
