Callum Kennedy made his league debut, and Jerel Ifil was also recalled.
Swindon took the lead on 50 minutes after an own goal from Peter Murphy.
Lee Peacock came close for Swindon hitting the bar, with Paynter and McGovern.
The referee upset alot of Swindon fans by constanly waving play on after a number of fouls. At one point two Swindon players needed treatment and all that was given was a throw in.
Cox then hit the bar himself with an overhead kick.
Then as been happening with most recent games Carlisle hit a later equaliser o 87 minutes with a goal from Paul Thirlwell.
Overall an average game, and yet another draw, but Swindon have drawn far too many games recently and if you were to draw every game in a season you would still get relegated.
