Laws said: "We are delighted to be in the draw for the next round - who knows what will come out?
"From a financial point of view it is a great result for us and it will already help us to strengthen.
"If we get a big name in the draw it is an incentive for both teams. Today wasn't a spectacle but we did our job.
"We did not play particularly well but I was delighted with the commitment that my side showed. We defended well throughout and in the second-half, Barnsley basically had one shot at goal.
"It's nice to take them to our place, it's a small pitch and it doesn't suit a lot of teams."
Tykes boss Godjon Thorjonson felt that his side should have converted posession into goals, while also insisting that he was confident ahead of the replay..
He said: "It was out own fault. We had the majority of possession and created chances that I felt that we should have taken.
"But goals win games and it was our own fault that we are not in the next round already.
"We are struggling in front of goal and that has been the story of our season.
"But at least we are in the draw. We are confident we can win the replay."
