How do you set the value of a currency field?

[___miked___]

Been messing around with this for over an hour.   Simply trying to add to dollar amounts together and display the total in a third currency field.   Really can't be that hard, so what am I doing wrong?

Here's my code:

function onChange(control, oldValue, newValue, isLoading, isTemplate) {

      if (isLoading || newValue === '') {

          return;

    }

    var tot = 0;

    var f1 = parseInt(g_form.getDecimalValue('field1'));   // field1 is first currency field.

    var f2 = parseInt(g_form.getDecimalValue('field2')); // field 2 is second currency field

    tot = f1 + f2;

    g_form.addInfoMessage(tot);   // checking the value here and getting the correct sum of the above two fields.

    g_form.SetValue('total_fields', tot);   //   <===This throws the error below.

}

Here's my (latest) error message:

var currencyCode = current.base_rate.getCurrencyCode();

I tried setting f1 without 'parseInt,' and tried using getValue rather than getDecimalValue, but neither worked.

I have a feeling the problem is right in front of me but I'm just not seeing it.

Any help would be much appreciated.

Have you defined your instances default currency?

Where do you do that?

Can give a try like below,

var f1 = g_form.getValue('field1');   // field1 is first currency field.

var f2 = g_form.getValue('field2'); // field 2 is second currency field

var tot = parseFloat(f1) + parseFloat(f2);

g_form.addInfoMessage(tot);   // checking the value here and getting the correct sum of the above two fields

g_form.SetValue('total_fields', tot);   //   <===This throws the error below.

Thanks for the reply and suggestion but here's what I found:

    o Using getValue returns the currency code and amount (USD;30).

    o parseFloat returns null.

    o setValue throws onChange script error: TypeError: g_form.SetValue is not a function function () { [native code] }

Whereas the original code returns the numeric values and did the addition correctly -- but still threw an error when I tried to write that sum to the field_totals field.

            var tot=0;

            var f1 = g_form.getDecimalValue('field1');   // field1 is first currency field.  

            g_form.addInfoMessage(f1);   // checking the value here and getting the correct sum of the above two fields

            var f2 = g_form.getDecimalValue('field2'); // field 2 is second currency field

            g_form.addInfoMessage(f2);

            tot = f1 + f2;

            g_form.addInfoMessage(tot);

            g_form.setValue('total_fields', tot);   //   <===This throws the error: onChange script error: TypeError: value.indexOf is not a function function () { [native code] }

So, it looks like the problem is in writing to the total_fields currency field.   Any thoughts?   Thanks again for your input.
