Cheltenham manager Mark Yates admitted his team has questions to answer after they slumped to a second away defeat in four days - a 4-1 loss at Chesterfield.
The home side cruised to back-to-back wins at the Proact Stadium through goals from Chris Atkinson, Sam Togwell, Marc Richards and Jack Lester with Kaid Mohamed replying for the visitors.
It was another bleak away day for Cheltenham who were beaten at Rotherham on Saturday and Yates said: "We have gifted them goals at the wrong time and didn't execute what we were trying to do particularly well.
"We got back to 2-1 and should have built on that but within minutes we were back to a two-goal deficit and chasing the game again.
"The players are hurting because no one likes to lose two games on the spin. We are third in the league and we're not going to hit the panic button but we have to go back to basics and be strong, competitive and organised.
"We have to get back to doing what we are good at. For the last couple of games we've not done that and we've been found wanting."
Chesterfield boss Paul Cook said: "The shape, balance of our team and passing was first-class.
"You must respect Cheltenham, they are a very strong team in this league but at times our passing and desire to get on the second ball was absolutely terrific.
"The lads were a credit to the club but we won't get carried away, we've said we just want to improve and we want our fans to be confident in the fact we are going to work hard. Along the way we will have bad results but if we all stick together we will have a good chance of having success.
"You must have competition for places and you must fear for your place in the team. You need a depth of squad to have success and it proved we have a nice balance to the squad."
