Kelly,

The location issue should not prevent your students from clocking in, and the business directly behind the hospital would still fall within the acceptable radius so the entry should not even flag.

Can you have the students that are claiming to have this issue make sure that they are trying to clock in for the correct day? Trying to clock in on the wrong day would prevent the student from clocking in. Since the schedule ques clock-ins for 24 hours prior to a shift, they might have multiple days they can click.

Let me know if that is the issue. If not, a screenshot would be helpful of what occurs when the students say they cannot clock in.
