Curly Brackets, finding text,,, must be Simple

[rplim2016]

Hi Mr. Excel users,

Is it possible for Curly brackets to produce a Cell Value answer?

Example..

In this case, a:a values are unique numbers, therefore, 1 is the only answer I can get in b:b

={if(a:a=1,b:b)}... now, what formula should I use to get the value align in b:b?
