Defendant appeals the sentence imposed after he pled guilty to robbery in the first degree, ORS 164.415. He contends that the court erred by not allowing him to collaterally attack the constitutionality of his prior juvenile adjudications in the sentencing process. The state concedes that the court erred. We agree. State v. Stewart/Billings, 321 Or 1, 892 P2d 1013 (1995).

Conviction affirmed; remanded for resentencing.
