Your Assignment, Should You Choose to Accept It
Now you do some on your own: Change the three Snoring Event fields in the same way by calculating the Snoring surcharge field from the rate and count fields and then locking the rate and surcharge fields (Figure 14).
Figure 14 You are now smart enough to change the other fieldsSnoring Surcharge and This Month’s Totalto locked, calculated fields. So do it, already.
When you’re done with that, turn the This Month’s Total field into a calculated field whose value is the total of the Wake-ups charge and Snoring surcharge fields.
When you’re done with that, sit back, relax, and drink something cool and refreshing. You’ve earned it!
