In a close contest, United's Gallagher had a shot blocked by Cotter, and Phillips did the same to Chertsey's ex-Hayes striker Dave Pearce.
These were the best opportunities in a quiet first half. The second period continued in much the same way. Davies saw a header cleared off the Town line by Cash and Carmichael volleyed just over.
Chertsey's Denton hit the bar, but the drama came in the final minute. A slip by Mark Newson let in Pearce and he passed sideways to Harrak who ?scored'. A flag by the Assistant Ref had already been raised and, after a delay, the Referee strangely awarded Chertsey a free kick.
After the kick was blocked, the final whistle sounded and Mr Hintze got surrounded by the irate home side. Certainly a strange decision was made, to the delight of United who got away with a point.
