Hello LaCrews,
After looking over your screenshot again we noticed that the 'To Field Name' name is blank. To help you better understand why we need this field to be filled think of the following scenario.
You wanted to find all activities scheduled between July 1st and July 31st. There is an activity scheduled for you to travel to Detroit to meet with a customer with DueDateStart of June 30th, 9 pm and DueDateEnd of July 1st, 1am. You then learn that your flight will be delayed by a few hours which means that you'll be stuck there all day July 1st and need to cancel all appointments for that day. If you were just concerned with DueDateStart, this appointment wouldn't show up in your calendar for July 1st, but since you are looking at both DueDateEnd and DueDateStart you know that you wouldn't be able to make it back to the office for July 1st appointments and need to cancel them.
Hence for “within date range” we need 4 values:
1. The “From Field”, which is the field that contains the starting date of scheduled jobs, usually DueDateStart.
2. The “To Field”, which is the field that contains the ending date of scheduled jobs, usually DueDateEnd.
3. The “Beginning Date” is the starting point for the date range, so in our example July 1st.
4. The “Ending Date” is the ending point for the date range, so in our example, July 31st.
I would like you to fill 'To Field Name' with a field name (if you are not sure which field to use, you can try DueDateEnd) and let me know if you still see the message.
