Hi globaltelemetrics and welcome to the forum,
I think the first sheet was making more sense than the new one. With the second I am not even sure where the results would have to go.
Now, if you do want to consider the first sheet you can use this array formula:
***Enter with Ctrl+Shift+Enter key combination
In A7 and drag formula to the right
=INDEX(Data!A$2:A$19,MATCH($A3&$B3&$C3,Data!$A$2:$A$19&Data!$B$2:$B$19,Data!$C$2:$C$19))
