simple code problem - adding variables acquired from prompt()

I need help with this piece of code please:


for(count=1; count<4; count++)
{
number=prompt("Enter a number please");


total=(number+number+number);
}

document.write(total);

My problem lies in the line with total=.
I can't figure out how to add all the results aquired from number's prompt function. Can someone please help?

Try this


var i, number, total = 0;

for(i = 1; i < 4; i++){
number = prompt("Please enter a number", "");

total += number;
}

document.write(total);

Thanks, but it doesn't work...

Can anyone else help please?

Sorry I missed something out


var i, number, total = 0;

for(i = 1; i < 4; i++){
number = prompt("Please enter a number", "");

total += parseInt(number);
}

document.write(total);

parseInt(number,10)

or even better

Number(number)

Thank you!!
