Cambridge United extended their unbeaten Blue Square Bet Premier run to seven games with a draw at Dartford.
Harry Crawford opened for the Darts when he converted Tom Bonner's cross.
But Michael Gash netted his eighth of the season for the U's when his free-kick wrong-footed on-loan Fulham goalkeeper Marcus Bettinelli.
Bettinelli made amends though with two saves in stoppage time to deny Gash and substitute Robbie Willmott and keep his side five points above the visitors.

Dartford manager Tony Burman told BBC Radio Kent:
"We could have said on chances it was a fair result.
"I'm just pleased we haven't lost. We've taken four points off Cambridge which is a great achievement for us.
"The players gave their all on Boxing Day and today and [having played] on heavy pitches, they're absolutely shattered.
"Cambridge were tired as well. It was one of those days where if one team scored a second goal, the other team wouldn't have got it back."
