Linking To Form.

Hi there, Im a little stuck here, my problem is im making a house insurance form where you enter data into the feilds and the calculations link back to create the end result amount i cant seem to get the right values in the form i have all the variables correct but just linking the two is where i need a little help where have i gone wrong? and what do i need to change in order to make it work.

Here is my code so far:

Expand|Select|Wrap|Line Numbers

 
<script language="javascript" type="text/javascript">

function houseInsurance( ){

var basePay = (a*0.0015)+(b*0.012)

var x = (basePay*1.15)

var y = (basePay*1.05)

var  totalPremiums = (x+y)*1.10

var result = c*totalPremiums

return result;

}

function calculate( ) {

var a = parseInt (document.form.housevalue.value)

var b = parseInt (document.form.contentsvalue.value)

var c = parseInt (document.form.noclaimbonus.value)

document.form.total.value = result

}

</script>
 
<body>

<form name = "houseInsurance"><h1>House Inurance:</h1>

House Value<br>

<input type = "Text" value = "Enter Amount" name = "1">

<br>

Contents Value<br>

<input type = "Text" value = "Enter Amount" name = "2">

<br>

No Claim Bonus<br>

<input type = "Text" value = "Enter Amount" name = "3">

<br>

<input type = "button" value = "result" Name = "click"

onClick = "calculate()">

<br>

Total<br>

<input type = "Text" value = "Total" name = "4">

</body>

i cant seem to get the right values in the form

What specificly is not right? Getting the wrong number, not getting a number at all, getting an error message?

just linking the two is where i need a little help

Linking what two to what?

Here is my code so far:

Expand|Select|Wrap|Line Numbers

<script language="javascript" type="text/javascript">

function houseInsurance( ){

var basePay = (a*0.0015)+(b*0.012)

var x = (basePay*1.15)

var y = (basePay*1.05)

var totalPremiums = (x+y)*1.10

var result = c*totalPremiums

return result;

}

function calculate( ) {

var a = parseInt (document.form.housevalue.value)

var b = parseInt (document.form.contentsvalue.value)

var c = parseInt (document.form.noclaimbonus.value)

document.form.total.value = result

}

</script>

<body>

<form name = "houseInsurance"><h1>House Inurance:</h1>

House Value<br>

<input type = "Text" value = "Enter Amount" name = "1">

<br>

Contents Value<br>

<input type = "Text" value = "Enter Amount" name = "2">

<br>

No Claim Bonus<br>

<input type = "Text" value = "Enter Amount" name = "3">

<br>

<input type = "button" value = "result" Name = "click"

onClick = "calculate()">

<br>

Total<br>

<input type = "Text" value = "Total" name = "4">

</body>

I am assuming there must be some missing code here.

1. Almost none of the JavaScript lines are terminated with semi-colons.

2. I do not see where the houseInsurance() function is ever acutally called. Is there code that was left out.

3. The houseInsurance() function is accessing variables named a,b,x, and y that do not seem to be declared anywhere.

4. The calculate( ) function accesses a variable named result that does not seem to be declared.

5. The calculate( ) function seems to be trying to access input fields with IDs housevalue, contentsvalue, and noclaimbonus. There are no fields in the HTML with those IDs.
