"We didn't play with much tempo in the first half and didn't create much at all," Town boss Clark told BBC Radio Leeds after the match.
"In the second half we stepped it up a bit and created some chances, but we just couldn't get it in the back of the net.
"We didn't play to the levels we have been of late, but we kept a clean sheet and took a point, so we will not be too sad about this result.
"We are still unbeaten at home this season and will take the positives from this game and bounce onto the next one."
