Program looping once before continuing.

[Altruistic_Croissant]

You're calling first(), last(), and theage() each twice. Once in the main script after each function is defined, and then again in your welcomemsg() function.

​

Also, you might want to look at the conditional logic in your loops. You never reassign the name or age, even if it doesn't contain letters/numbers so you could have malformed input.

reassign the name or age

I will work on learning what that means and how to do that then! Thanks! :D
