Your path information appears to be correct.
Are you selecting rows 2 through 5 before you start the import process?
Do you receive any errors during the import process? If so, what are they?
CAREFULLY review the Excel Add-in Guide. All the information I have provided to you could've been found in the guide in the section titled "Formatting Requirements" . For example:
"Designate a Requirement Type column. For each requirement, specify the requirement type."
You have not specified a requirement type for your very first requirement.
