The Daggers came back from a goal down to see off the Shots as they turned in a fine display.
A delighted Still said: "We had great desire. We went a goal down when we could have been in front, but the main thing was the desire.
"We went behind early on, but we came back strong and I never lose faith with these players.
"In the last five games we've had three wins and a draw which is fantastic.
"Sometimes our players might find it a bit strange that we are in a position where we are challenging to get out of this league, but I think this would have helped them get to grips with the reality of it."
