Problem with index and match

[mcva]

Hi, I need to fill column V with the text that is in column AA if three conditions are matched: A=AA; $B$1=AB; J=AC. I have included some colors in the following figure to facilitate the analysis.
I have used the formula that is also shown in the figure however it is not working. What's the problem with my solution?
Thank you

Not sure what this is doing , as mentioned - and counifs() perhaps with an IF may help
