Group count doesnt work

[Guest]

I am trying to count how many tickets each employee sold. I have a staff
header with the employee name. Then I have detail that shows the ticket
numbers sold by that staff member. Then I have a staff footer where I am
trying to count the tickets from the detail, but it doesn't work. I made a
text box, put it in the staff footer and this is the control source. (I
found it in my Dummies book)

count([ticket number])

When I go to run it I get an error. Any suggestions?

The expression in the Control Source of the text box needs to start with =.
Try:
=Count([ticket number])
