CONCAT Formula NAME? Error

[chloeyal]

Hi,
I'm looking for a formula to pull the Names of Items that have the soonest start date, including those that start on the same date.
I have attached a worksheet as an example of my problem, in which I've tried to use the CONCAT formula but am coming up with the NAME? error.
The output I'm looking for in the Formula column is "Name1, Name1 & Name1" for example.

Please could someone help me solve this error or let me know of a better formula to use.
Thank you.

Welcome to the forum.

CONCAT is not the issue: the 'curly' quotes you have used are, though. Change them to straight quotes:

=IF(A2<>"", IF(OR(B2<E2, D2=""), A2, IF(OR(E2<H2, G2=""), CONCAT(A2," &@ ", D2), IF(OR(H2<K2, ILP6=""), CONCAT(A2,", ", D2," &@ ", G2)))), "")
