(Client Side Scripting)Calculating values in child tables

to calculate the values of child tables, you can use the following functions:

frappe.ui.form.on("[CHILD TABLE DOCTYPE]", {
	[CHILDTABLEMULTIPLE1]: function(frm, cdt, cdn) {
		var d = locals[cdt][cdn];
		var total = 0;
		frappe.model.set_value(d.doctype, d.name, "[CHILDTABLEPRODUCT]", d.[CHILDTABLEMULTIPLE1] * d.[CHILDTABLEMULTIPLE2]);
        frm.doc.[CHILDTABLEFIELDINPARENT].forEach(function(d) { total += d.[CHILDTABLEPRODUCT]; });
        frm.set_value('[PARENTDOCTYPETOTALFIELD]', total);
	}
});
frappe.ui.form.on("[CHILD TABLE DOCTYPE]", {
	[CHILDTABLEMULTIPLE2]: function(frm, cdt, cdn) {
		var d = locals[cdt][cdn];
		var total = 0;
		frappe.model.set_value(d.doctype, d.name, "[CHILDTABLEPRODUCT]", d.[CHILDTABLEMULTIPLE1] * d.[CHILDTABLEMULTIPLE2]);
        frm.doc.[CHILDTABLEFIELDINPARENT].forEach(function(d) { total += d.[CHILDTABLEPRODUCT]; });
        frm.set_value('[PARENTDOCTYPETOTALFIELD]', total);
	}
});
