Noobie if() statement

[simontheak]

I feel kind of silly for not being able to see what's wrong with this, but it's starting to drive me mad.

So could someone tell me where I'm going wrong?

  else if(submit_form.price.value == "" || isNaN(submit_form.price.value)=="true"){
  alert( "Please enter a price." );
    submit_form.price.focus();
    return false;
  } 

Thanks very much,

You should use single quotes in the alert statement.

I've tried that Curtis, but I'm not having any more luck I'm afraid ...

[Sorccu]

alert(true == "true"); // false

Can you guess what's wrong?

[AlienDev]

else if ((submit_form.price.value == "") || (NaN(submit_form.price.value)=="true")) 

Try that

Doesn't matter if you use single or double quotes in an alert. Adding more parentheses will also not solve the issue that Sorccu points out.
