This is the JavaScript forum. Java and Javascript are entirely different programming languages, in spite of the confusingly similar names.

Try this:-

Code:

<HTML>
<HEAD>
</HEAD>
<BODY>

TITLE 1 <input type = "text" name= "t1" id = "t1" size = "5"><br>
TITLE 2 <input type = "text" name= "t2" id = "t2" size = "5"><br>
TITLE 3 <input type = "text" name= "t3" id = "t3" size = "5"><br>
TITLE 4 <input type = "text" name= "t4" id = "t4" size = "5"><br>
TITLE 5 <input type = "text" name= "t5" id = "t5" size = "5"><br>
<input type = "button" value = "Calculate Result" onclick = "calc()"><br><br>
RESULT<input type= "text" name = "result" id = "result">

<script type = "text/javascript">

function calc() {
var valid = true;
var sum = 0;
var values = new Array();
for (var i = 1; i<=5; i++) {
values[i] = parseInt(document.getElementById("t"+i).value);
if (isNaN(values[i]) || values[i] < 0 || values [i] > 10000) {
valid = false;
} 
}
if (!valid) {
alert ("You must enter only numbers from 0 - 10000 in all five boxes")
return false;
}
values[1] = values[1] * 0.79;
values[2] = values[2] * 0.53;
sum = (values[1] + values[2]) * values[3];
sum = sum * values[4] * values[5];
sum = (sum/10).toFixed(2);  // sum to 2 decimal places
document.getElementById("result").value = sum;
}

</script>


</BODY>
</HTML>

I hqave assumed that the input values are integers (whole numbers). If not, alter
values[i] = parseInt(document.getElementById("t"+i).value);
to
values[i] = parseFloat(document.getElementById("t"+i).value);

Suggest you pay the $5 to a charity of your choice.
