Counting Data Arrays

Nice to meet you I am new to BUBBLE.
I am currently developing a shift creation tool for my job.
We have a fixed shift time and we are trying to keep track of the list of applicants by putting users into the fixed time slots.
The problem here is that I need to keep track of the number of people submitting shift requests each month.
Is there a good way to count the number of users in the fixed time slots?

To keep track of the number of users in the fixed time slots, you can utilize the “:count” expression. This allows you to count the number of users associated with each time slot. Check out the attached image for reference on how to use it.
