Adding number

[everisk]

Hi,

 

I have a function where I'll add value of all array (named amnt) after a button is clicked. However, the function doesn't seem to loop correctly (it seems to be running forever) and didn't output the totalAmnt value in the last line. Below is my code. How do I fix this? Thanks.

 

function calculateTotalAmnt() {
var loopno = parseFloat(document.getElementById("serviceno").value);
var totalAmnt = parseFloat(0);
var i;
for(i = 0; i<=loopno; i++) {
	var toget = "amnt["+i+"]";
	totalAmnt = parrseFloat(totalAmnt) + parseFloat(document.getElementById(toget).value);
}

document.write("here"+totalAmnt); //this output doesn't show
}

There is a much easier way to do this, if you show your HTML I can give you an example. As for your javascript right now, you have:

totalAmnt = parrseFloat(totalAmnt)...

 

There are two 'r's in your parseFloat method, but I'm pretty sure it would work the same without that method there at all.

Hi Lemmin, thank you noticing my mistake. Silly me. After i take out the extra 'r' it works. Thank you so much for your help.
