Alexander wants Town response
Graham Alexander urged Fletwood to use the heartbreak of their JPT defeat to Chesterfield as motivation for the rest of the season.
Jon Parkin gave Fleetwood a 1-0 win in the second leg of their northern area final but Chesterfield went through 3-2 on aggregate to reach Wembley for the second time in three seasons - where they will meet Peterborough on Sunday March 30.
Chesterfield took a 3-1 advantage into the game and created the better chances in the first half, with Jimmy Ryan, Marc Richards and Jay O'Shea all forcing Chris Maxwell into saves.
Substitute Eoin Doyle had a great chance to finish the contest when he headed over from six yards in the 83rd minute but Parkin gave Fleetwood hope when he turned in a left-wing cross in the 90th minute.
However, Chesterfield survived six minutes of stoppage time to return to Wembley, where they lifted the trophy in 2012 by beating Swindon.
Alexander admitted losing out on the showpiece was painful. He said: "It's hurting for the players and for me because we would have loved to get to Wembley for everyone at the club.
"But we've got to make sure we have this pain inside us to drive us on to better things in the league. It's a glorious failure which we don't want. We want ugly wins and ugly success but if you are going to go out, this was the way to go out, we gave it right good go against a good team.
"We wanted to come here and be in the game after an hour and then give it everything we had and I thought the lads were fantastic, they left everything out on that pitch."
