I have been trying to work on this for a while now, and this is on excel

In cell H10, enter an INDEX function that will use a nested INDIRECT reference to the Dept named range listed in column C (C10), and use the Reason field in column B (B10) as the row number to return for the department name in the referenced named range. Nest the function inside an IF function so that issues currently displaying as a 0 will display as a blank cell. Resize the column width as needed.

** I got this much of the formula

=INDEX(INDIRECT("Dept"),Reason)

but it only recalls and displays the Dept column contents. I need it to recall the Dept and display the Reason, I think? Then at that point, how would I get this into an IF statement?

I feel like I dont understand the instructions, and I know I am not that great on excel.
