here external javascript:

function validateform() {     if (document.getelementbyid("name").value == "") {         alert("you cannot leave field blank. please enter name");     } else {         alert("field ok");     }       if (document.getelementbyid("address").value == "") {         alert("please enter address");         document.getelementbyid("address").focus();         return false;     }      if (isnan(document.getelementbyid("postcode").value.length < 4)) {         alert("your postcode not valid");     } else {         alert("you have entered postcode correctly");     }       if (document.getelementbyid("email").value.length < 5 || document.getelementbyid("email").value.indexof("@") == -1) {         alert("please enter email min 5 chars , include @ symbol");         document.getelementbyid("email").focus();         return false;     }       {         if (isnan(document.getelementbyid("creditcard").value.length < 16)) {             alert("please enter creditcard number");         } else {             alert("please enter valid credtcard number");           }         alert("thank submission!");         return true;     }

i think, there's 1 bracket much.

{  // <---- remove this.     if (isnan(document.getelementbyid ("creditcard").value.length < 16))
