The young Glovers will be hoping for more success in the competition after defeating Premier League outfit West Brom at the Hawthorns in the last round.
They also have the added incentive of a potential away tie at either Aston Villa or Blackburn Rovers in the fifth round of the competition.
Tickets for tonight’s match in Hertfordshire are priced at £5 for adults, £2.50 for under-16s and concessions, and £1 for under-12s.
The tie must be decided tonight, there will be no replay. Should the scores remain level at 90 minutes, extra time and then penalty kicks will be used to determine the winner.
