Simple Javascript for form validation doesn't work -


so, have written form , simple javascript validate user input. thing is, works until add third function, validatehash, takes hashtag inputed textbox , checks if has hashtag @ beginning. sent code friend, , said on pc works fine (checks if fields filled, , checks if hashtag correct), while on mine skips every function , submits data php page without checking anything. using firefox, , he's using chrome, tried latter same results. there wrong in code itself?

<!doctype html> <meta charset="utf-8"> <link rel="stylesheet" href="style.css" /> <script language="javascript" type="text/javascript">   function validateform() {    if(validate(document.form.song.value) && validate(document.form.hashtag.value))      if(validatehash(document.form.hashtag.value))        return true;     else     {       alert("please fill fields");       return false;      }   }    function validate(text) {     if(text==null || text=="")       return false;     else       return true; }    function validatehash(text) {     if(text.charat(0) != "#") {       alert("insert hashtag correctly");       return false;       }     else       return true; }  </script>  <form action="format.php" name="form" method="post" class="basic-grey" onsubmit="return validateform()">   <h1>anisongs form     <span>fill text in fields</span>   </h1>    <label>     <span>song lyrics :</span>     <textarea id="song" name="song" placeholder="max 120 characters" maxlength="120"></textarea>   </label>    <label>     <span>anime hashtag :</span>     <input id="hashtag" type="text" name="hashtag" placeholder="#loghorizon" maxlength="20"/>   </label>       <span>&nbsp;</span>     <input type="submit" class="button" value="submit" />     <input type="reset" class="button" value="cancel" /> </form>

well, issues brackets. js fancies them, , without them on single lines ifs wouldn't start work.
