I have the following function on over 140 rows in a project plan:
=IF(TaskCheck@row = 1, "Task Done", IF(ISBLANK(Predecessors@row), "Ready to Begin", IF(INDEX(TaskCheck:TaskCheck, VALUE(LEFT((Predecessors@row), 2))) = 1, "Ready to Begin", "Don't Start (Predecessor Incomplete)")))
If the predecessor is not complete the task will show in gray and say "Don't Start (Predecessor Incomplete)".
The function is listed the same way for all rows but for rows 100-120, it is not working correctly. Instead of "Don't Start (Predecessor Incomplete)", it says "ready to begin". It should only say ready to begin of the predecessors are complete.
I tried copying over to a new sheet, deleting the rows and starting from scratch. Rows 100-120 are still incorrect.
