Keith Bertschin's side also had to overcome playing with just ten men for 40 minutes of the second half after James Blake was sent off for two bookable offences.
The hosts took the lead just three minutes before the half time break through former Leeds United and Huddeersfield striker Clyde Wijnhard who is on trial with The Saddlers.
Blake received his marching orders five minutes into the second period but Blues equalised on 64 minutes through Peter Till.
