how can sum of two variables and populate in third one on catalog form?

[Chandra18]

Hi team,

There are three fields total amount, P.Amount, and L.Amount. here total amount = P.Amount + L.Amount.

All fields accept number values on the catalog form, I want if the value gets a change of any variables (P.Amount + L.Amount) the total amount value should be changed.
How can I achieve this?
Thanks

Hi @Chandra18,

just use setvalue to updated total into Total variable.

g_form.setValue("total_amount_variable", sum);

Thanks,

Hi @Chandra18,

Correcting my previous response. You have to create 2 On-change Catalog client scripts as -

Catalog Client scripts 1:

Variable - P Amount

function onChange(control, oldValue, newValue, isLoading) {
	if (isLoading || newValue == '') {
		return;
	}

	var value1 = newValue; // p-amount
	var value2 = g_form.getValue("l_amount");
	value2 = value2 || 0;

	var sum = parseInt(value1) + parseInt(value2);
	g_form.setValue("total_amount", sum);

}

Catalog Client scripts 2:

Variable - L Amount

function onChange(control, oldValue, newValue, isLoading) {
	if (isLoading || newValue == '') {
		return;
	}

	var value1 = g_form.getValue("p_amount"); // L Amount
	value1 = value1 || 0;
	var value2 = newValue;
	
	var sum = parseInt(value1) + parseInt(value2);

	g_form.setValue("total_amount", sum);

}

Make sure to update your variable names.
