Tom Murphy snatched an injury time goal for the Whites making sure the game ended all square.
The manager said "It is a bit of a kick in the teeth, the lads are very disappointed in there.
"It is my job to pick them up again and get them ready for Dartford on Tuesday night."
Rovers had several chances to extend their lead before Murphy's late leveler however Darrell is confident his team will start scoring those chances.
"I thought we defended well we just weren't clinical enough at the other end of the field.
"I've got great belief in the boys and we will start scoring these chances."
Dartford are up next for Rovers at the Memorial Stadium on Tuesday night and Darrell insists that his team have to put it right.
"We should be sat here with three points but we have to put it right on Tuesday night.
"It's a tough league, but no one will be wanting to play Bristol Rovers that's for sure.
"The supporters were brilliant again and have every right to be disappointed but we just have to make sure that we get three points on Tuesday night."
