Opinion by

William Giltinan appeals a Montogomery County Common Pleas Court order which affirmed a six-*97month suspension of his driver’s license for refusal to submit to a breathalyzer test. 75 Pa. C. S. §1547.

Our scope of review is limited to determining whether there has been an error of law or whether the findings of the lower court are unsupported by competent evidence. Appeal of Capozzoli, 63 Pa. Commonwealth Ct. 411, 437 A.2d 1340 (1981). In that the court below is the finder of fact and the arbiter of credibility and because the record supports the court’s conclusion that Giltinan refused the breathalyzer test, we will affirm on the able opinion of Judge Smillie, Pa. D. & C.3rd (1980).

Affirmed.
