there is something else wrong, this (which is basically what you want as i understand) should work:

var user;

function choose(choice)
{
  user = choice;
  alert("You got the value " + user);
}

function showUser(str)
{
  var buttonValue1 = user;
  alert("checking buttonvalue1  " + buttonValue1);
}

choose('test');
showUser('whatever');
