ORDER
PER CURIAM:
Kenneth Schauer appeals from the judgment of the Circuit Court of Nodaway County dismissing his action relating to a previously entered child support modification on the basis of res judicata and collateral estoppel. As a formal opinion would offer no precedential value, we provide the parties with a memorandum of law explaining our ruling. Finding no error, the judgment of the trial court is affirmed. Rule 84.16(b).
