Please help with this simple java script code

Gecco · 5 Jan 2009 at 16:02

Here's what I need to do:
Delivery is charged @ 1£ per mile above 3 miles

if (distance is less than 3 miles)
Inform of free delivery
else
If (distance is between 3 and 12 miles)
Inform of delivery charge
else
Inform of maximum delivery distance 12 miles

Code:

<SCRIPT LANGUAGE = "JavaScript">

// A delivery charge program 

var distance;
var extraDistance; 

distance = window.prompt('Please enter the distance in miles', '');
distance = parseFloat(distance);




if (distance <= 3)
{
	document.write('You qualify for free delivery');
}
extraDistance = distance - 3
else
 if (distance  > 3 && <= 12);
  {      
    document.write(' You will be charged ' + extraDistance + '£');
}
else 
  {        
    document.write('Our maximum delivery distance is 12 miles!');
}

</SCRIPT>

I don't know where i have gone wrong. Your help is greatly appreciated.

Looks like you had a couple of formatting errors.

Code:

<SCRIPT LANGUAGE = "JavaScript">

// A delivery charge program 

var distance;
var extraDistance; 

distance = window.prompt('Please enter the distance in miles', '');
distance = parseFloat(distance);

if (distance <= 3)
{
	document.write('You qualify for free delivery');
}
else
{
	extraDistance = distance - 3;
	if (distance  > 3 && distance <= 12)
	{      
		document.write(' You will be charged ' + extraDistance + '&pound;');
	}
	else 
	{        
		document.write('Our maximum delivery distance is 12 miles!');
	}
}
</SCRIPT>

This is for Open University course M150 TMA 02. Next time, do your own homework for assignments and ask your tutor if you get stuck. BUSTED.

What does it matter who he asks? He's clearly made an effort :confused:

It's explicitly against the rules. If he attended his first tutorial, he would also have been treated to a lecture about how the OU tutors search forums like this for posts like his asking for help with coding.

The Assignments section of the Assessment Handbook contains this statement: ‘Posting your own assignments and/or tutor comments on an Open University forum, or on any other website, is not allowed (unless you are required to do so as part of your assignment).’
