I have edited the loop but still get only the literal string "sum +=

what do I need to convert this to the .value?
Ahh.. penny has dropped... I think.
Steven may correct me if I'm wrong on this but IIRC _javascript_ evaluates
symbols thus:
== (double =) means 'this is the content of'
= means 'this is the result of'
Not sure if that makes linguistic sense so here's an example:
a = 2 + 4 result - a = 6
a== 2+4 result - a is a string '2+4'
In other words I think you may have a == where you want a =, or vice versa.
Also, it may be the single quotes around the _expression_ telling the
script to enclose the lot in a string;
vat_low = 'sum += parseInt( document.splitfm.vat_low' + i + '.value )';
Try:
vat_low = sum += parseInt( document.splitfm.vat_low' + i + '.value );
I notice as well that vat_low isn't given an initial value, so the
script may assume it's a string and not be calculating the value as a
mathematical value, but concatenating it as a string.
Kind regards,
