Scenario:
When importing task information into a project using a CSV file the import page shows the error 'Task 'X' is an invalid input for the task'.
(Check the attached picture)

Cause:
The error is thrown due to the '/' symbol in the task name.

Resolution:
Remove the '/' symbol from the task name in the CSV file before import. Edit the task name in the Web TimeSheet after the import is complete.

Note:
As of now the import utility does not support '/' within the task name.  The '/' symbol is used only for dates and, to separate project name and task names in the task name full path.
