It was Stockport who took the lead after 31 minutes after a close range goal by Stephen Gleeson after Swindon failed to clear the ball away.
Just after the break Swindon equalised with a goal from Craig Easton from the edge of the box on 48 minutes.
Swindon then went on to have much of the play in the second half, but couldn't score a second. Towards the end of the game Corr had a good chance, but blasted his shot high and over.
Overall an average game where a draw was a fair result. Swindon's next game is next Sunday at home to Millwall.
