Help on forms & tables - Problem getting rows & columns to calculate

This will not be possible in HTML alone. You will need to use some scripting (Java or VB) to get the calculations you're asking for.

If you are familiar with scripting it's really simple. Just add a little recalculate order button, or the script can do it automatically for you whenever one of the boxes change.

I don't really have the time to write out the script for your site since I'm being paid to work for someone else , but the first thing you'll have to do is name the form, it will be easier in the script to refer to the form name. I'll provide a little sample of some script that you can use on your site. For now let's say the form is called order.

<script LANGUAGE="javascript">
<!--
function computeForm(input)
{
form = document.order;

// Guard against empty values to prevent JavaScript Errors (NaN)

if (isNaN(form.r-item1price.value)) {
alert("Invalid input, use only numbers.");
form.r-item1price.focus();
}

if (isNaN(form.r-item1qty.value)) {
alert("Invalid input, use only numbers.");
form.r-item1qty.focus();
}

if (isNaN(form.r-item1total.value)) {
alert("Invalid input, use only numbers.");
form.r-item1total.focus();
}

if ((form.r-item1price.value == null ¦¦ form.r-item1price.value.length == 0)) {
form.r-item1price.value = 0;
}

if ((form.r-item1qty.value == null ¦¦ form.r-item1qty.value.length == 0)) {
form.r-item1qty.value = 0;
}

if ((form.r-item1total.value == null ¦¦ form.r-item1total.value.length == 0)) {
form.r-item1total.value = 0;
}
form.r-item1total.value = parseFloat(form.r-item1price.value) * parseFloat(form.r-item1qty.value);

}
//-->
</script>

That will do the first item in your order form, just repeat it for all the others. Then to total just add all the r-item1 - 8total boxes together. Then like I said before just assign this action to a button or an onchange event and everything should be fine. You can always give the total boxes read only access that way nobody can mess up the totals.

If you don't understand scripting I guess this was kind of pointless, if that's the case I hope this was a learning experience for someone

Later,

P.S. Any errors in the above script are due to the fact that it was written without testing, not advisable
