Trouble Setting a Variable True basing on an Imput

[VictorVictus]

What I want to do is to make the program check a list with names, and if it shows up in one of the lists automatically check the name as male or female

I'm still confused. You want to check "a list", and then if it shows up "in one of the lists" do something. Is it one list or multiple lists? And what do you mean by "check the name male or female"? The name in the list, or the name the user gave you?

Can you give me a small example of the lists you are talking about?

thanks for your help, doubt has been solved already, still I thank you! I intended to make two lists of names and if they coincided with the imput they would be classified as either male or female.
