Hi there!

I'm a newbee here... I just wanted to ask a little help.

We just started discussing javascripting. And our teacher gave us a workshop. It is quite simple but still, i am having troubles. It is a simple payroll system. There are required inputs and it should yield outputs based on the inputs. And the inputs shall be acquired using prompt.
_________________________________________________________________

Here are the requirements of the Payroll System:

Input: (all shall be acquired by PROMPT)
1. Name of employee
2. No. of days worked
3. Rate per day

Output: (shall be displayed by DOCUMENT.WRITE)
1. Name of employee
2. Rate per day
3. No. of days worked
4. Gross pay (= Rate per day * No. of days worked)
5. Deductions (10% of gross pay)
6. Net pay (= Gross pay - Deductions)

Another requirement is to do the scripting externally (saving it as filename.js)
__________________________________________________

I have gone through with the first few parts but i couldn't do with the Deductions and Net pay. I coded the Deductions and Net pay calculations as if i was using Microsoft Excel or OpenOffice Calc. After successfully making the first four required outputs, I proceeded with making the codes for the Deductions. When I tested it all the required outputs were displayed except the Deductions output. When I made made the codes for the Net pay I tried to refresh the page to test if it would work, but this time nothing prompted. Nothing completely appeared. No prompt box. All there was was a blank white page.

Below is the entire javascript i did.


//var name= prompt("Enter employee name: ", ' ');
//alert("Enter employee name: ");
name= prompt("Enter employee name: ");
nDays= prompt("Enter no. of days worked: ");
rate= prompt("Enter rate per day: ");

document.write("Name of employee: " +name);
document.write("<br>Rate per day: " +rate);
document.write("<br>No. of days worked: " +nDays);
document.write("<br>Gross pay: " +rate*nDays);
document.write("<br>Deductions: " + (rate*nDays*0.1));
document.write("<br>Net Pay: " + (rate*nDays - (rate*nDays*0.1));



I'm pretty sure it needs a lot of corrections. What errors should i correct? and What should I use with the Deductions and Net Pay requirements? And any suggestions, please? Please help me with this simple problem which i couldn't make right. Please, and thank you in advance!
