Swindon started well, but it was Chesterfield who took the lead on 19 minutes with a goal that looked offside from close range from Paul Hall.
Swindon had chances to equalise with a free kick from the edge of the area, but Gurney had his shot tipped over the bar, and away for a corner which was wasted.
In the second half Jack Smith cleared the ball off the line, and Rhys Evans also had to make an early second half save to keep the score down.
Ashan Holgate who started on Monday came on to replace Michael Pook. Holgate had another good game putting in some good crosses, and coming close to scoring himself.
After a foul in the box Swindon were awarded a penalty on 63 minutes. With no regular penalty taker this season Bouazza took it, and scored to make it 1-1.
Swindon came close to getting a winner after some of Holgate's crossed but they failed to find Fallon in a suitable location.
The game finished 1-1 which was a fair result with both sides having chances. The draw leaves Swindon equal bottom on 23 points with Rotherham and Milton Keynes, but things are looking a lot better than 3 months ago when Swindon were 8 points adrift.
