Swindon earned a last-minute winner against Barnet thanks to a stunning Royce Brownlie 25-yard strike.
The visitors had taken a surprise lead through Nicky Bailey after 17 minutes when he fired in a left-footed shot.
But Ricky Shakes equalised for Swindon with a strike from the right-hand edge of the box after 53 minutes.
