Can I select/filter with a variable table name in the expression

[MJvanEwijk]

Hello, I am trying to sort if the following is possible:
Using a select/filter expression where to Table Name depends on a choice I made in the form before.
So the Table Name in the expression depends on condition before…

SELECT(Table Name[First Name], TRUE)

I am trying to have a IF expression; IF Table Name= x, SELECT(x[First Name],…), IF Table Name=y, SELECT(y[First Name],…), etc

Thanks Muk

Hope someone can help, any expression/idea will help
