StartA X: <INPUT TYPE = Text NAME = x SIZE = 5  value ="0">

  Two B Y: <INPUT TYPE = Text NAME = y SIZE = 5 value ="1">
Three D W: <INPUT TYPE = Text NAME = w SIZE = 5 value ="0"> 

W2+: <INPUT TYPE = Text NAME = w2 style="background-color:#444999"  SIZE = 5 value = ("0") >

W3:<INPUT TYPE = Text NAME = w3 SIZE = 5 value = "0" >
<P>
Total Z: <INPUT TYPE = Text NAME = z SIZE = 5 value = "0">
<P> 
<p>
<Input Type = Button NAME = b1 VALUE = "Pluss One" onClick = calculate(),colourchange() >


</FORM>

<SCRIPT language = JavaScript>
function calculate() 
{
var randomnumber=Math.floor(Math.random()*99)
A = document.frmOne.x.value
B = document.frmOne.y.value
D = document.frmOne.w. value

A = Number(A)
B = Number(B)
D = Number(D)
C = (A + B)
D = (D + 1)
E = randomnumber

document.frmOne.z.value =  C
document.frmOne.x.value = B
document.frmOne.w.value = D
document.frmOne.w2.value = E 
document.frmOne.y.value = A+1 
document.frmOne.w3.value = A+B+C+D+E
}
</SCRIPT>
<SCRIPT language = JavaScript>
function colourchange()
{
var randomnumber2=Math.floor(Math.random()*999999)
if 
B > 1
then w2= "background-color:#randomnumber2"
else
w2= "background-color:#987654"
}
</SCRIPT>

- Attach a click listener to the button.
- When the button is clicked, generate 3 random numbers between 0 and 255.
- Set the backgroundColor property to use the rgb() colour system with those 3 numbers representing Red, Green, Blue:

element.style.backgroundColor = "rgb("+randomRed+","+randomGreen+","+randomBlue+")";

is this along the right lines please?

</html>
<FORM NAME = frmOne>

W2+: <INPUT TYPE = Text NAME = w style="background-color:#123456;"  SIZE = 5 value = "0" >
<P>
Total Z: <INPUT TYPE = Text NAME = z SIZE = 5 value = "1">
<P> 
<Input Type = Button NAME = b1 VALUE = "Pluss One" onClick = calculate() colourchange()  >
</FORM>

<SCRIPT language = JavaScript>
function calculate() 
{
A = document.frmOne.w. value
A = Number(A)
C = A+1
document.frmOne.w.value =  C
document.frmOne.z.value = C+1 
}
</SCRIPT>
<SCRIPT language = JavaScript>
function colourchange()
 {
	  var red=Math.floor(Math.random()*256)
	   var green=Math.floor(Math.random()*256)
	    var blue=Math.floor(Math.random()*256)

w.style.backgroundColor = "rgb("+randomRed+","+randomGreen+","+randomBlue+")";
}
</SCRIPT>

`its not working yet though .
`1. click listiner = fuction ?
`2. var blue=Math.floor(Math.random()*256) = var # < 256 = check yes 2 s64 no = donot pass GO.
3. dos element = name ?
4. have I put it in the right place ?

Your codes are non-standard and wrong syntax. You can't call two function with only one click event.
And also the variable are not matching (randomRed,randomGreen,randomBlue), I don't see these three variable defined. It must be (red,green,blue).
Try with below:

<html>
<body>
<form name="frmOne">
W2+: <input type="text" name="w" style="background-color:#123456;" size="5" value="0" />
<p>
Total Z: <input type="text" name="z" size="5" value="1" /></p>
<p> 
<input type="button" name="b1" value="Pluss One" onClick="calculate()" /></p>
</form>
<script language="javascript" type="text/javascript">
function calculate() 
{
A = document.frmOne.w.value;
A = Number(A);
C = A+1;
document.frmOne.w.value =  C;
document.frmOne.z.value = C+1;
return colourchange();
}
</script>
<script language="javascript" type="text/javascript">
function colourchange()
 {
	  var red=Math.floor(Math.random()*256)
	   var green=Math.floor(Math.random()*256)
	    var blue=Math.floor(Math.random()*256)

		document.frmOne.w.style.backgroundColor = "rgb("+red+","+green+","+blue+")";
}
</SCRIPT>
</body>
</html>

It should work. Hope this help!
