Validation of empty fields in JavaScript and displaying text inside <p> tag -

this guestbook validation trying make. text in <p> tag not getting changed , don't know why. me validate form:

function frmvalidate() {     var nmchk = document.forms["guestform1"]["name"].value;     var cmntchk = document.forms["guestform1"]["comment"].value;     if (nmchk == null || nmchk == "") {         var namep = document.getelementbyid("namep");         x.innerhtml = "name must filled out";         return false;     } else {         return true;     }     if (cmntchk == null || cmntchk == "") {         var cmntp = document.getelementbyid("cmntp");         x.innerhtml = "comment must filled out";         return false;     } else {         return true;     } } 

instead of

    var namep = document.getelementbyid("namep");     x.innerhtml="name must filled out"; 

you want

    var namep = document.getelementbyid("namep");     namep.innerhtml="name must filled out"; 

but when execute first if else, quit function, want :

function frmvalidate() {     var nmchk=document.forms["guestform1"]["name"].value;     var cmntchk=document.forms["guestform1"]["comment"].value;     if (nmchk==""||nmchk==null) {             var namep = document.getelementbyid("namep");             namep.innerhtml="name must filled out";             return false;     }     if (cmntchk==""||cmntchk==null){             var cmntp = document.getelementbyid("cmntp");             cmntp.innerhtml="comment must filled out";             return false;     }     return true; }
