What is the appellant's burden to affirmatively show error?

We begin with a brief review of appellate practice. "A judgment or order of a lower court is presumed to be correct on appeal, and all intendments and presumptions are indulged in favor of its correctness." (In re Marriage of Arceneaux (1990) 51 Cal.3d 1130, 1133.) It is the appellant's burden to affirmatively show error" 'This is not only a general principle of appellate practice but an ingredient of the constitutional doctrine of reversible error.' " (Denham v. Superior Court (1970) 2 Cal.3d 557, 564.)
