Excel index/match formula issue

Question

I have an issue with index/match formula in excel. I fill row A and B automatically (first name and last name) with index/match formula depending on a employee ID on C column which is dynamic (I pull it from another sheet and it refreshes/changes automatically)

When one or more employees are removed, my formula is messed up in some cells (A and B columns) related to column C.

Match($C sometimes becomes match(#REF, and sometimes it has wrong cell number for example it has match($c5 instead of match($c6 because some employees are removed automatically)

Please see a picture and a hope everything will be much clearer.

Appreciate help.

Answer 1

try changing the source data into a true table with structured references (Ctrl + T) that may get rid of your REF errors when the source changes.
