United manager Russ Wilcox was pleased with his side's progression, after a 2-0 victory against Chesterfield in the Johnstone's Paint Trophy.
The Iron took a first half two goal lead through Sean McAllister - his first competitive goal for the club - and Gary McSheffrey, enabling them to be in the hat for Round Two of the competition."I'm pleased we got through," Wilcox told The Iron Player.
"I think it's important that we progressed through to the next stage of the competition, with it being a chance to go to Wembley. It's probably our only opportunity to get to Wembley, so we have to take it."
Scunthorpe went into the game making just two changes from the weekend's 2-1 win over Walsall, with them both enforced, according to the United boss.
"We need to begin to look at consistency," he continued.
"That's important for our league form. I didn't make many changes as we have been doing well of late and I didn't want to change that.
"We want to be competitive in this competition, so I'm pleased that paid off."
The visitors went down to ten men six minutes from time when Jack Broadhead was dismissed for a second bookable offence. Despite the one man advantage, United failed to breach the Spireites defence any further.
"We can always do things better and again, we will work on that," he said.
"I thought that our game management when they went down to ten men was disappointing and it will be something we look at.
"We need to pass the ball better in those circumstances and exploit the advantage.
"I looked for us to get the ball and keep the ball and play two touch, getting it around the pitch and create a few more opportunities in front of goal.
"We gave the ball back to them too cheaply, but they're a good quality side - it doesn't matter how many changes they've made."
He added: "We managed to see the game out though, with a clean sheet, which was very pleasing."
