if else if not working 'Javascript '

Question

function checkforblank(){
  if (document.getElementById('fname').value == "help","help ","HELP","HELP ") {

    showText("#msg2", 'commands:', 0, 100);
    showText("#msg3", '#1 MAIN, back to MAIN menu', 0, 100);
    showText("#msg4", '#2 PORT, nav to PORT page', 0, 100);
    showText("#msg5", '#3 ABOUT, nav to ABOUT page', 0, 100);
    showText("#msg6", '#4 CONT, nav to CONTACT page', 0, 100);
    showText("#msg7", '#5 STOP, stop all', 0, 100);
    //(document.getElementById('textarea').document.write('jajajajajjaja'());
    return false; 
  } 
  else if (document.getElementById('fname').value == "main","main ","MAIN","MAIN "){       
    alert('hello');

  }
  else{
    alert('error');
     return false;
  }

}

my else if statement doesnt execute code but instead it does the code in the if statement..

I believe that's because your if statements are not an appropriate way to check if a value is contained in a collection... see this question on determining if an array contains a value — user3334690, Commented Apr 10, 2014 at 19:27
The comma operator doesn't create a collection of values for == to check. For that, you'll need an Array to search within, such as described in "Determine if string is in list in JavaScript." — Jonathan Lonowski, Commented Apr 10, 2014 at 19:28

This one doesn't work. You have to separate all different values with the OR operator ||.

if (document.getElementById('fname').value == "help" || document.getElementById('fname').value == "HELP ") {
