Sorting script: slight modification?

[sallyoz]

I hope!

At the moment this code relies on the sequence q_0, q_1, q_2, q_3

I would like to change it so it is q_00, q_01, q_02, q_03 to allow me to sort.

As a novice I have tried a few things but no luck. I would love some assistance from you gurus

return;
}
}
// check if a quantity entered
if (form.sub_tot.value==0) {
alert("You haven't ordered anything.");
return false;
}
}

function setFocus(fld) {
fld.focus();
fld.select();
}

function isPosInt(frm,fld,val) {
var re = /^\d+$/
if (!re.test(val)) {
alert("Please enter whole numbers only." + val);
if (document.forms[frm.name]) { // protect ns4 in case of nesting
setTimeout("setFocus(document.forms['"+frm.name+"'].elements['"+fld.name+"'])",100);
} else {
fld.focus(); fld.select();
}
return false;
} else return true;
}

str = "0" + str;
}
var decpoint = str.length - decplaces;
return str.substring(0,decpoint) + "." + str.substring(decpoint,str.length);
}

function validate() {
if(document.entry_form.name.value.length <1) {

I'm going to make the assumption that q_0, q_1, ect are elements in your form, probably to hold the "quantity" of items. In that case, why don't you just them in an array instead?

[sallyoz]

Sorry it didn't paste in full.

Array up the top of the script which needs to correspond with form fields. The array is then the q_0, q_1. At the moment because it is dynamically generated it's putting them in the wrong order.

Thanks for your assitance

What exactly isn't working? My best guess is that you need to call doTotals() after you generate your form...
