ORDER

Father appeals from the trial court’s judg-. ment modifying his child support obligation. We affirm. The judgment of the trial court is supported by substantial evidence and is not against the weight of the evidence; no error of law appears. An extended opinion would have no precedential value. The parties have been furnished with a memorandum for their information only, setting forth the reasons for this order affirming the judgment pursuant to Rule 84.16(b).
