Calculating fields…

Copy linkTweet thisAlerts:

Hi there…

I’m trying to calculate some fields, but it’s not working well.. ?

I’ve got 3 fields like 17n01, 17n02 and 17n03. The total of the numbers in these fields should be displayed in another field subtotal01.

In my example it’s not calculating correct. E.g. the values are 1,3 and 5. The subtotal should be 9. But in my form is displays 135.

This is my code:

[CODE]
totaal17n01 = document.bestellen.totaal17n01.value;
totaal17n02 = document.bestellen.totaal17n02.value;
totaal17n03 = document.bestellen.totaal17n03.value;

sub01 = (sub01 + totaal17n01 -0);
sub01 = (sub01 + totaal17n02 -0);
sub01 = (sub01 + totaal17n03 -0);

document.bestellen.sub01.value = sub01;
[/CODE]

Can anyone help me?

@avaOct 19.2005 — Sure I can help. All items in the textfields are strings (text) so you need to set them to integers with the ParseInt() function.

Replace: [CODE]sub01 = (sub01 + totaal17n01 -0);
sub01 = (sub01 + totaal17n02 -0);
sub01 = (sub01 + totaal17n03 -0);[/CODE]

With:[CODE]sub01 = parseInt(totaal17n01) + 0 + parseInt(totaal17n02) + parseInt(totaal17n03);[/CODE]And it'll work.
