I have a formula that reads like this
='AVALANCHE SCHEDULE'!C1

Avalanche Schedule being the name of another sheet in my workbook.
It is a schedule that is very long. As a date passes, I go into the
schedule and delete the top row (row 1). Everything then shifts up. The
next date is now in Row 1, however the data does not populate. I get a REF#
error and I don't understand why, because there is data in Avalanche Schedule
C1

Please help. I have also tried ='Avalanche Schedule'!$C$1

THanks
